Wedging Slip Assembly For Supporting A Pipe Or Rod Patents (Class 175/423)
  • Patent number: 9695662
    Abstract: A retention system for limiting axial and radial movement of a wellbore lock ring. The retention system includes pins for resisting axial movement of the lock ring and assemblies for limiting radial outward movement of the lock ring. The lock ring circumscribes and couples to a wellbore hanger. The pins project radially from the hanger into the lock ring and into slots, where the slots extend a distance along the inner surface of the lock ring. The assemblies also project radially into the hanger and each have a portion that registers with a channel on a lower end of the lock ring. Lock ring outer radial movement is limited by contact between the portions of the assemblies and inner surfaces of the channels.

A grip activation assembly acts between the body and the grip surface to increase a grip ratio of radial load upon the gripping assembly relative to axial displacement of the body relative to the grip surface. The grip activation assembly includes a motor driven load screw to create relative axial displacement of the body relative to the grip surface.

  • Patent number: 7861773
    Abstract: Retrievable bridge plug used in oil and gas wells comprises a setting and anchoring mechanism, a locking and releasing mechanism and a sealing and anti-adhering mechanism. The bridge plug in which a self-lock mechanism is placed can be lowered through an coiled tubing or wireline, and provide reliable bi-directional sealing, and can be taken out by a specific tool after setting, in order to be used repeatedly after simple maintenance. By replacing its mandrel, the bridge plug can be refitted into a squeezing bridge plug, a conventional one and a hook-wall bridge plug to be used in a temporary/permanent and selective blocking operation. Also, the bridge plug can be associated with other downhole tools to perform well test, layer protection and snubbing.

  • Patent number: 7832470
    Abstract: The present invention allows for the connection of multiple sections of drill pipe in a mouse hole by securing a given section of pipe in the hole and delivering a rotational force to secure that pipe section to another section of drill pipe placed above it over the mouse hole. In some embodiments, the rotational force may be provided by the support unit of the present invention. In alternative embodiments, the rotational force may be provided by an outside source such as an iron roughneck, with the support unit of the present invention holding the drill pipe section in a stationary position as such force is delivered. The unit then allows the connected pipe sections to be lowered and secured so the process can be repeated to connect multiple sections of drill pipe together in the mouse hole. The multiple sections of drill pipe may then be retrieved as a unit, and attached to the pipe string already being used to drill the well.

  • Patent number: 7743856
    Abstract: A slip spool includes radially disposed actuators for radially moving slip blocks between a loose encirclement position in which they surround the tubing string and a cached position in which the slip blocks clear an axial passage of the slip spool. The slip spool further includes axially disposed actuators for axially displacing the slip blocks between the loose encirclement position and an engagement position in which the slip blocks are seated within a slip bowl of the slip spool so that a weight of the suspended tubing string causes the slip blocks to tightly grip the tubing string. The slip spool facilitates positioning and repositioning of the tubing string in the wellbore and can be used for supporting or snubbing a tubing string in a live well bore.

  • Patent number: 7665551
    Abstract: A gripping apparatus for supporting a tubular includes a longitudinal opening extending therethrough. A bowl is formed on an inner wall of the housing to provide an incline surface for one or more gripping members. As the gripping members are move down along the incline, the incline causes the gripping members to move radially toward the tubular and contact the tubular. In one embodiment, the housing comprises two body portions coupled together using one or mores hinges. In one aspect, the bowl is formed as a recess in the inner wall of the housing. The hinges of the housing are progressively curved to accommodate the recess bowl, thereby increasing the tubular size handling capacity of the gripping apparatus. In another embodiment, the apparatus may include guide keys that mate with guide slots formed on an outer surface of the gripping members to minimize the rotational movement of the gripping members relative to the housing.

  • Patent number: 7527093
    Abstract: A self-tightening safety tubular clamp for suspending a casing string or other tubular member within a well. In one embodiment, a base has an opening for receiving the casing string. A first gripping member and an opposing second gripping member are each adapted to frictionally engage the casing string. First and second pivot arms include parallel linkages for supporting the gripping members. Each parallel linkage is pivotally secured to the base at one pivot pair, and pivotally secured to one of the gripping members at an upper pivot pair. Frictional contact with the gripping members allows the weight of the casing string to move the pivot arms downward. As the pivot arms move downward, the gripping members move downward and inward into engagement with the casing string. The parallel linkages ensure that gripping surfaces of the gripping members remains vertical, in alignment.
