Description

BACKGROUND

In the petroleum industry, wells are drilled into the surface of the Earth to access and produce hydrocarbons. The process of building a well is often split into two parts: drilling and completion. Drilling a well may include using a drilling rig to drill a hole into the ground, trip in at least one string of casing, and cement the casing string in place. The casing string is used to define the structure of the well, provide support for the wellbore walls, and prevent unwanted fluid from being produced. The casing string is cemented in place to prevent formation fluids from exiting the formation and to provide further structure for the well.

After a casing string has been placed in the well, the annulus located between the casing string and the wellbore wall must be cemented completely (i.e., to surface) or partially. Cementing is done by pumping cement from the surface, through the inside of the casing string, and up the outside of the casing string (the annulus) to the required height. Oftentimes, the slurry of cement is followed by another type of fluid and/or a wiper plug to push the remainder of the cement out of the inside of the casing and into the annulus, leaving a small amount of cement inside of the casing string. The cement is left to harden before the next section of the well is drilled or the well is completed.

DETAILED DESCRIPTION

In the following detailed description of embodiments of the disclosure, numerous specific details are set forth in order to provide a more thorough understanding of the disclosure. However, it will be apparent to one of ordinary skill in the art that the disclosure may be practiced without these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description.

Throughout the application, ordinal numbers (e.g., first, second, third, etc.) may be used as an adjective for an element (i.e., any noun in the application). The use of ordinal numbers is not to imply or create any particular ordering of the elements nor to limit any element to being only a single element unless expressly disclosed, such as using the terms “before”, “after”, “single”, and other such terminology. Rather, the use of ordinal numbers is to distinguish between the elements. By way of an example, a first element is distinct from a second element, and the first element may encompass more than one element and succeed (or precede) the second element in an ordering of elements.

Regarding the figures described herein, when using the term “down” the direction is toward or at the bottom of a respective figure and “up” is toward or at the top of the respective figure. “Up” and “down” are oriented relative to a local vertical direction. However, in the oil and gas industry, one or more activities take place in a vertical, substantially vertical, deviated, substantially horizontal, or horizontal well. Therefore, one or more figures may represent an activity in deviated or horizontal wellbore configuration. “Uphole” may refer to objects, units, or processes that are positioned relatively closer to the surface entry in a wellbore than another. “Downhole” may refer to objects, units, or processes that are positioned relatively farther from the surface entry in a wellbore than another. True vertical depth is the vertical distance from a point in the well at a location of interest to a reference point on the surface.

During the drilling operations of an oil or a gas well fluids may be circulated into and out of the well to help with the operations such as drilling, completing, or working over. FIG. 1 shows an example of circulation of a fluid 100 through a well 102 during an operation where the fluid 100 is pumped into the well 102 through a conduit 104 such as a drill string and circulated out of well 102 through an annulus 106 formed between the well wall and the exterior surface of conduit 104. Fluid 100 may be, for example, a specially designed fluid known commonly as drilling “mud” or other completion, stimulation, or workover fluids. In the operation of drilling, the circulating fluid may be drilling mud and may carry back cuttings from the drilling face to the surface. The fluid may be collected at the surface, reconditioned, and reused. In the wellbore, the fluid may also be used to maintain a predetermined hydrostatic pressure on the walls of the well, which in turn prevents undesired influxes of hydrocarbons or other fluids from the well to the surface. The circulation may also maintain the integrity of the wellbore by applying pressure on its walls to prevent the walls from collapsing.

Another operation is known in the art as cementing for which the fluid is a cement slurry, hereafter cement. After a hole section has been drilled, a string of casing is run into a well and cemented in place by pumping cement through a tubular pipe such as conduit 104 inside of the casing or tubing string. An area of a well that is uncased, which means exposed to the rock formation without any casing, is known in the art as open hole. The cement slurry exits the conduit 104 at a downhole location. Continued pumping may cause the cement slurry to rise up annulus 106 between conduit 104 and the well wall. Next a cementing tool may be used to separate the column of cement slurry in conduit 104 from another fluid or substance such as a column of drilling mud used to push the cementing tool to the downhole location and in doing so, displace the column of cement with drilling mud. Displacing the cement slurry evacuates cement in the bore and replaces it with drilling mud. Cement slurry within annulus 106 may be filled to a desired height. The cement slurry may be allowed to harden. Cement that has hardened thereby forms a seal between the exterior surface of conduit 104 and the well wall of well 102. One of the challenges in drilling and workover is the proper cleaning of the tubular profile after the cement job.

Cleaning the tubular profile entails removal of contaminants that are disposed on portions of the tubular profile walls and that are contained within the bore of conduit (104). Cement slurry that remains in the tubular profile may adhere to a portion or portions of the tubular profile if the cement slurry is allowed to harden, therefore cement that is still in the slurry condition may be easier to remove than cement that has been allowed to harden. Accumulated cement is an example of the contaminants contained within conduit 104 to be removed from within portions of the tubular profile. Contaminants such as accumulated cement may prevent certain tools from passing or setting inside the tubular profile. Accumulated cement may also cause plugging of downhole tools or obstructing the passage or travel of downhole tools along the portion of the tubular profile in which the accumulated cement is contained. Accumulated cement may increase the cost of drilling with lost time due to downhole tool damage. Accumulated cement along portions of tubular profiles may also limit the utilization of tubulars in the long term. Embodiments disclosed herein present a system and method to remove contaminants from a portion of a bore of a tubular pipe in a well by pumping in a wiper plug with multi-sized fins and to circulate through the plug.

FIGS. 2A-2B show an example of a wiper plug system 200 that may be used to perform a cementing wiper run. Wiper plug system 200 includes a wiper plug 202 and a nipple 250. FIG. 2A shows the external layout of wiper plug 202 including four sizes of a wiper 204 along with a landing profile 220. FIG. 2A shows a plurality of multi-sized wipers 204 disposed on wiper plug 202, which in this embodiment is shown as quantity four multi-sized wipers. Although quantity four wipers 204 are shown, the wiper 204 quantity may be any appropriate quantity such as, without limitation, at least one, at least two, or at least three multi-sized wipers. Each wiper 204 may be a fin 206 with a fin outside diameter 208. Each fin 206 may be configured to develop a reaction force to pressure applied to a fin sealing side 210 of each fin 206. Each fin 206 may be configured to transfer the reaction force to the wiper plug 202. Each fin 206 may be configured to permit none, some, or all pressure passage on a fin bypass side 212 fin bypass side 212. Each fin 206 may be configured to transfer substantially reduced reaction force to the wiper plug 202 resulting from pressure applied to each fin bypass side 212 fin bypass side 212. Wiper plug 202 therefore may be unidirectional with fins 206 configured with a fin sealing side 210 and a fin bypass side 212. The fin 206 sizes may differ primarily in variations to the fin outside diameter 208 of each fin 206. Fin outside diameter variations may tailor each wiper to produce an optimum cleaning function to correspond with variations in internal diameters of the tubular profile of conduit 104. In addition, the fins 206 have an exterior peripheral surface that is radially expandable. The radially-expandable peripheral surfaces are adapted to seal against the inner surface of the tubular profile of conduit 104. Fins 206 may be made of robust materials such as natural rubber, synthetic rubber, polyurethane, thermoplastics, flexible concrete, spring steel, etc. Some embodiments of the fin materials may include fiber reinforcements such as glass fiber or carbon fiber. In accordance with one or more embodiments, the conduit 104 may be production tubing. Fins 206 may be disposed on an upper end 224 of wiper plug 202.

As shown in FIG. 2A, landing profile 220 of wiper plug 202 shows a plurality of arms 242, which in this embodiment is shown as quantity two arms. Although quantity two of arms 242 are shown, the arms 242 quantity may be any appropriate quantity such as, without limitation, at least one, at least two, or at least three arms. Arms 242 extend outward from an external profile 222 of wiper plug 202. At least one of a locking dog 244 locks the wiper plug 202 to the nipple 250. Arms may be part of a spring mechanical locking mechanism 240. Landing profile 220 may be disposed on a lower end 226 of external profile 222 of wiper plug 202. Landing profile 220 positions the wiper plug 202 in the conduit (104 FIG. 1) and is configured to cooperate with the tubular profile to travel in a downhole direction in the conduit (104 FIG. 1) to the nipple 250.

FIG. 2B shows the internal layout of wiper plug 202 representing a path 230 of the fluid through the plug. Wiper plug 202 has an internal bore 228 that forms the path of the fluid. A flapper 232 of a flapper valve is disposed in the wiper plug 202 and is configured with a closed position and an open position. Flapper 232 closed position may substantially prevent flow of fluid 100 through internal bore 228. Flapper 232 may be configured to change from the closed position to the open position and from the open position to the closed position in a manner as a flapper valve is known in the art. Flapper 232 may be configured at a flapper edge 234 with a means for coupling the flapper 232 to wiper plug 202. A means for coupling at the flapper edge 234 may be configured to translate flapper 232, to rotate flapper 232, or to both rotate and translate flapper 232 thus to move flapper 232 from the closed position to the open position and from the open position to the closed position. Examples of a means for coupling flapper edge to wiper plug 202 include a hinge, a ball and socket, a pivot joint, etc. Flapper 232 open position may substantially permit flow of fluid 100 through internal bore 228. Flapper 232 may be configured to selectively control flow of fluid 100, such as to move to be open to fluid flow in an opening direction such as from uphole to downhole, and to move to be closed to fluid flow in a closing direction, such as from downhole to uphole. Flapper 232 may be configured to be maintained, held, or latched in the closed position to be in a disabled condition to substantially prevent fluid flow in the opening direction. Flapper 232 may be configured to release from the disabled condition to an enabled condition. In the enabled condition, the flapper may remain in the open position such as through the use of gravity, a spring, a latch, or other means, or the flapper may operate as a unidirectional flow valve such as a flapper valve as is known in the art.

The flapper may be translatably coupled to the wiper plug 202. The means of translatably coupling may include fasteners such as studs, nuts, screws, bolts, and pins engaging the flapper, e.g., through a hole or slot in the flapper. The means of translatably coupling may include springs such as coil springs in compression or tension, constant force springs, or torsion springs. The coupling may further use a dovetail slot on one or both of the flapper or the wiper plug 202 and a mating dovetail rail on the other of the flapper or the wiper plug 202. The coupling may include one or more sliding bearings such as a ball bearing, cylindrical roller bearing, spherical roller bearing, tapered roller bearing, and/or journal bearing on one or both of the flapper or the wiper plug 202 and a mating sliding surface.

The flapper may be rotatably coupled to the wiper plug 202. The means of rotatably coupling may include fasteners such as studs, nuts, screws, bolts, and pins engaging the flapper, e.g., through a hole or slot in the flapper. The means of rotatably coupling may include springs such as coil springs in compression or tension, constant force springs, or torsion springs. The coupling may include one or more rotatable bearings such as a ball bearing, cylindrical roller bearing, spherical roller bearing, tapered roller bearing, and/or journal bearing on one or both of the flapper or the wiper plug 202 and a mating shaft or axle, pin, stud, or rod on the other of the flapper or the wiper plug 202.

Flapper 232 may be maintained, held, or latched in the disabled condition by a means for holding such as a flapper disabler 236. Although in this embodiment the flapper disabler 236 is shown as a single shear pin, flapper disabler 236 may use a plurality of shear pins, and flapper disabler 236 may be any appropriate holder such as, without limitation, a spring, a ball-spring catch, a grab latch, etc., that maintains the flapper 232 in the closed position to prevent flow of fluid along path 230. Flapper disabler 236 may be configured to release the flapper 232 from the disabled condition. Release of flapper 232 may occur if a release force is applied to a flapper opening side 238 of flapper 232 that meets or exceeds the holder force holding the flapper 232 in the disabled condition. Release force may be applied by a pressure acting in the opening direction on the surface of the flapper opening side 238 of the flapper 232 such as a pressure in conduit 104. For instance, a plurality of shear pin holds the flapper 232 in the disabled condition and if a breaking force resulting from pressure in conduit 104 acting on the surface of the flapper opening side 238 of flapper 232 exceeds the holder force, then the breaking force may break the shear pin such as by shearing. Breaking the shear pin will allow circulation, i.e., flow through wiper plug 202 in the opening direction.

FIG. 2B also shows a latch profile 252 disposed in the nipple 250 such as a seating nipple as is known in the art. The latch profile 252 may cooperate with landing profile 220 to position wiper plug 202 within nipple 250. Nipple 250 may be disposed in conduit 104 and may form part of conduit 104. Circulation may occur after landing wiper plug 202 into latch profile 252 of nipple 250 and shearing the flapper disabler 236, such as a shear pin, of the flapper 232.

FIGS. 3A-3D show the wiper plug 202 in position to engage the latch profile 252 for positioning wiper plug 202 in the conduit 104. Specifically, FIGS. 3A-3D show a sequence of positions of the wiper plug 202 and arms 242 as the wiper plug 202 shown inserted in a tubular pipe, such as conduit 104, is lowered into and engages the latch profile 252 of nipple 250 to position wiper plug 202 within conduit 104 and remove contaminants from tubular profile. In some embodiments tubular pipe may be production tubing. In FIG. 3A, the wiper plug 202 may be inserted into conduit 104 oriented with the lower end 226 of wiper plug 202 downhole. The fin outside diameter 208 of fin 206 may engage the tubular profile of conduit 104. Pressure applied to fin sealing side 210 results in a reaction force transferred to wiper plug 202. Reaction force that exceeds friction force of peripheral surfaces sealing against the inner surface of the tubular profile of conduit 104 may cause wiper plug 202 to travel in a direction opposite the pressure applied to the fin sealing side 210.

As shown in FIG. 3B, as pressure is continued to be applied, wiper plug 202 may continue to travel to reach a landing position 392 within nipple 250. The landing profile 220 of the wiper plug 202 is shown having cooperated with the latch profile 252 of the nipple 250. FIG. 3C shows that the internal profile of the nipple 250 has cooperated with the spring mechanical locking mechanism 240 to trigger the arms 242 to engage the latch profile 252 of nipple 250 to position the wiper plug at the landing position 392. FIG. 3D shows the relative position of arms 242 with respect to latch profile 252 before arms 242 reach latch profile 252. FIG. 3E shows the cooperation of arms 242 with latch profile 252 after arms 242 reach latch profile 252. Spring mechanical locking mechanism 240 acts to extend arms 242 radially from external profile 222 of wiper plug 202 landing profile 220. Before, when, or soon after arms 242 engage latch profile 252, at least one of the locking dogs 244 locks the wiper plug 202 to the nipple 250. For example, at least one of the locking dogs 244 attached to the wiper plug 202 may lock directly to the nipple 250, the latch profile 252, or the internal profile. Alternatively, at least one of the locking dogs 244 of wiper plug 202 may lock arms 242 in the extended position at the latch profile 252.

Pressure applied to the fin sealing side 210 of fins 206 may move the wiper plug 202 to landing position 392 at which wiper plug 202 may be considered in a landing position 392. If pressure continues to be applied to the wiper plug 202 in the landing position 392, then the wiper plug 202 no longer moves down the conduit 104 and pressure may increase and may exceed the holding force of the flapper disabler 236.

FIGS. 4A-4F show the nipple 250 installed on conduit 104 and a sequence of positions of the wiper plug 202 within conduit 104 as the wiper plug 202 travels down conduit 104, engages the latch profile 252 of nipple 250 to position wiper plug 202 within conduit 104, and removes contaminants 400 from tubular profile. FIG. 4A shows nipple 250 installed on an end of conduit 104 and contaminants 400 adhered to the tubular profile of conduit 104, such as production tubing. FIG. 4B shows running wiper plug 202 with at least three multi-sized wipers 204, landing profile 220, and a valve with flapper 232 into the tubular pipe. Running the wiper plug 202 into the tubular pipe includes inserting wiper plug 202 into conduit 104 with lower end 226 facing downhole. FIG. 4B shows pressure being applied to the top of the wiper plug 202 and onto the fin sealing side 210 of fins 206 to move wiper plug 202 in a downhole direction. Fins 206 of wiper plug 202 remove contaminants 400 from the tubular profile before, when, or after fins 206 moving down tubular pipe pass over contaminants 400. FIG. 4B shows contaminants 400 adhered to a portion of the tubular profile of conduit 104 before wiper plug 202 travels to that portion. FIG. 4C shows the wiper plug in the landing position 392 and contaminants 400 having been removed from the tubular profile. Contaminants 400 such as cement and other debris are removed to the open hole.

FIG. 4D shows the wiper plug in the landing position 392 and pressure continuing to be applied to the uphole side of wiper plug 202. FIG. 4E shows the wiper plug in the landing position 392 and pressure continuing to be applied to the uphole side of wiper plug 202 and the pressure acting on the flapper opening side 238 developing a force that exceeds the holding force of the flapper disabler 236. FIG. 4E shows that a flapper disabler 236 such as a shear pin held the flapper 232 in the disabled condition up until, before, or after a breaking force resulting from pressure in conduit 104 acting on the surface of the flapper opening side 238 of flapper 232 exceeded the holder force of the flapper disabler 236. FIG. 4E shows the well being circulated after having broken the shear pin allowed circulation, i.e., fluid 100 to flow through wiper plug 202 in the opening direction.

FIG. 5 depicts a flowchart in accordance with one or more embodiments. More specifically, FIG. 5 illustrates a method for installing nipple 250 on conduit 104 and removing contaminants from within the tubular pipe. Further, one or more steps in FIG. 5 may be performed by one or more components as described in FIGS. 1-4 (e.g., the wiper plug 202). While the various steps in FIG. 5 are presented and described sequentially, one of ordinary skill in the art will appreciate that some or all of the steps may be executed in different orders, may be combined or omitted, and some or all of the steps may be executed in parallel. Furthermore, the steps may be performed actively or passively.

Referring to FIGS. 3A-3E, FIGS. 4A-4F, and FIG. 5 together, initially, the wiper plug system 200 is provided (S500). The wiper plug system 200 is deployed first by installing nipple 250 with a latch profile 252 at the end of a tubular pipe such as conduit 104 (S502). The wiper plug 202 having an internal bore 228, at least three wipers 204, a landing profile 220, and a valve is deployed next by running the wiper plug 202 in hole. Wiper plug 202 is run in hole by inserting the wiper plug 202 into conduit 104 with lower end facing downhole (S504). Next the conduit 104 is pressurized by pumping a substance such as drilling mud inside the tubular pipe and thereby applying pressure to the fin sealing side 210 of at least one fin 206 of at least one of at least three wipers 204. Pressure so applied moves the wiper plug 202 to landing position 392 thereby setting the wiper plug 202 mechanically in place on the latch profile 252. Radially-expandable peripheral surfaces of fins 206, adapted to seal against the inner surface of the tubular profile of conduit 104, scrape, wipe, clean, loosen, or otherwise remove from the tubular profile the contaminants 400 and debris as the fins travel over the tubular profile (S506). Next the pressure continues to be applied to the fin sealing side 210 and to the flapper opening side 238 and thereby the pressure increases within conduit 104. Pressure continues to increase until a breaking force resulting from pressure in conduit 104 acting on the surface of the flapper opening side 238 of flapper 232 exceeds the holder force of the flapper disabler 236. The breaking force breaks the shear pin or plurality of shear pins. Breaking the shear pin or plurality of shear pins enables the flapper 232 of the flapper valve and may allow circulation, i.e., flow through wiper plug 202 in the opening direction (S508). The wiper plug system 200 then is open for flow to circulate the well (S510).

Although only a few example embodiments have been described in detail above, those skilled in the art will readily appreciate that many modifications are possible in the example embodiments without materially departing from this invention. Accordingly, all such modifications are intended to be included within the scope of this disclosure as defined in the following claims. In the claims, means-plus-function clauses are intended to cover the structures described herein as performing the recited function and not only structural equivalents, but also equivalent structures. Thus, although a nail and a screw may not be structural equivalents in that a nail employs a cylindrical surface to secure wooden parts together, whereas a screw employs a helical surface, in the environment of fastening wooden parts, a nail and a screw may be equivalent structures. It is the express intention of the applicant not to invoke 35 U.S.C. § 112(f) for any limitations of any of the claims herein, except for those in which the claim expressly uses the words ‘means for’ together with an associated function.
