Alternatively, in embodiments the thru-holes 42 shown in
Generally, the embodiments of the clamp 2 can be located on the neck area (or different components) of the downhole equipment and/or ESP equipment 54. For example, embodiments of the clamp 2 may be placed on the outside or above/below the downhole equipment and/or ESP equipment 54 for downhole oil and gas production, or other production equipment including, but not limited to, gas separators, sand/solid separators, etc. In embodiments, a few of the purposes of the clamp 2 include, but are not limited to, the following: (1) providing standoff and/or centralization of an ESP string while the ESP string is conveyed downhole, when it is being operated, or when it is being retrieved back to surface; (2) securing a motor lead extension (MLE) or power cable of the ESP and any capillary (CAP), tubing lines, or sensor lines, such as electronic, tubing, or fiber optic, or any line that may run on the outside of the ESP string, as well as protecting the ESP string from the three methods of use/travel listed in (1); (3) the combination of (1) and (2); or (4) providing guided entry through reductions or rough areas in the downhole environment; this also is true for other type of downhole equipment. Thus, generally some of the purposes of the embodiments described herein may be to provide protection to the MLE cable, power cables, cap lines, and fiber optics, and/or other sensor lines of the ESP equipment 54, as well as guide the ESP equipment 54 safely downhole for installation, during operation, and back out of the hole during retrieval of equipment.
In embodiments, a plurality of clamps 2 may be used on the downhole equipment and/or ESP equipment 54, as illustrated in
The embodiments described herein provide many advantages over currently known methods. In embodiments, the components of the clamp 2 are designed to create an overall clamp assembly that is novel and serves the purposes of allowing the assembly to: be modular; be able to be used in multiple orientations and configurations making the assembly customizable on the spot, per job situation; have a mechanism that serves as an anti-rotation feature that is configurable and functions regardless of assembly orientation, wherein this feature interfaces with the ESP or other downhole equipment; employ the cable hold down clip 10, wherein the clip 10 is orientated per job criteria, but the modular design allows the clamp to be adjusted/turned/oriented to fit any alterations or new orientations; employ the rub bars 8, which are devices that stand the ESP or other equipment off from the downhole casing or hole surface, wherein the rub bars 8 protrude past the outer diameter of the equipment, further wherein the rub bars 8 are fastened to the main body of the clamp 2 either the clamp top 4 and/or the clamp bottom 6 via a hard mechanical interface preventing them from moving in the direction of conveyance, and further wherein the rub bars 8 may also be interchanged or flipped between other clamps and itself due to modularity; hold cables or cap lines by mechanical, external means that are capable of securing multiple sizes of the cables or cap lines regardless of size, order, or configuration; employ a clamp that may be adjustable, and yet all parts are contained to prevent parts falling down hole; and comprise an embodiment in which all parts are contained and there are zero loose parts when installation is taking place, and therefore, no risk of parts falling down hole to later cause damage to well and/or equipment. Further, in embodiments the clamp 2, as well as its various components, may comprise stainless steel, carbon steel, metallic or composite alloy, or the like. Additionally, in embodiments the clamp 2 may be fitted to any equipment as long as the size of the clamp 2 and equipment together allow the clamp 2 and equipment to fit within the wellbore.
Generally, the above describes improved downhole products for the protection and/or securing of cables, tubing, and the like, as well as methods of using the downhole products.
