Definitions

  • the present disclosure relates to the field of protection for cables or conduits, which are typically used in the wellbore industry for recovery of natural resources.
  • the disclosure relates to couplings to provide said protection.
  • a downhole may refer to a hole drilled for the purpose of exploration or extraction of natural resources, which may include water, gas or oil.
  • a corresponding well may be produced for extraction of said natural resource.
  • a downhole may include a wellbore or a drill hole.
  • the downhole is generally drilled into the Earth with a globally vertical trajectory. Local portions of the downhole may have a non-vertical trajectory, including substantially horizontal, for example for trajectory correction or to navigate around objects.
  • the trajectory may therefore serpentine.
  • a pipe may be located within a bore of the downhole, the pipe forming an extraction conduit for extraction of said natural resource between an extraction location and a transmission location.
  • An extraction location may include an underground location.
  • a transmission location include the surface of the ground, or a subsea surface.
  • the downhole may have an uneven internal surface, and may curve locally. This in turn presents difficulties in inserting and removing components, including the well pipe, from the downhole.
  • a well pipe is generally formed from a number of sequentially interconnected pipes. Adjacent pipes are connected by a coupling. When a well pipe is lowered into a downhole, the pipes are inserted into the downhole pipe-by-pipe. That is, a first pipe is inserted into the downhole, a coupling is used to attach said first pipe to a second pipe and so on.
  • Components including electrical submersible pumps (ESP), may be inserted into the downhole and require cabling for operation thereof.
  • Exampling cabling includes; ESP cables; control lines; umbilicals and; encapsulating bundles.
  • a run of the cable is generally between the outer surface of the well pipe and the surface of the down hole. Said cable run may be susceptible to damage, particularly proximal the coupling, e.g. since the coupling typically protrudes outwardly from the well pipe and/or the coupling may be displaced during use of the well pipe.
  • a cable protector may be implemented, inter alia, to reduce the risk of damage to said cabling proximal the coupling and/or to secure said cable generally.
  • a known cable protector currently marketed by Slingco R includes a pair of interconnected grippers.
  • a lower gripper grips the first pipe below the coupling, and an upper gripper grips the second pipe above the coupling.
  • a spine interconnects the first and second gripper, which spine extends contiguous an outer surface of the coupling.
  • the spine may also extend contiguous a portion of each pipe, proximal the coupling.
  • the spine is arranged to form a passage through which cabling can pass. Proximal the coupling, the cabling is secured within the passage, which may reduce said risk of damage.
  • Each gripper has an open and closed configuration. In the open configuration, the pipe is movable relative the gripper. In the closed configuration, the gripper grips the pipe by engagement with its outer surface.
  • the gripper includes two hingedly coupled arms. Each arm includes a series of teeth, which are arranged to interdigitate in the closed position. Each tooth has a passage formed therethrough. When interdigitated, a locking member is passed through passages of the teeth of both arms to second the gripper in the closed position.
  • a drawback is that the locking member may be dropped during insertion/extraction from said passage. If the locking member falls down the downhole, equipment located in the downhole may be damaged. Moreover, it may be difficult to retrieve a dropped locking member from the downhole.
  • a drawback is that positioning the locking member for insertion in said passages may be difficult, particularly in extreme environmental conditions, which are associated with a downhole.
  • the present disclosure provides a gripper.
  • the gripper may be for a cable protector.
  • the cable protector may be for protection of cables extending contiguous pipes.

With the arm in the closed position, and the catch engaged by the latch, the gripping system is retained in the engaged position for engaging the pipe. As the arm is moved to the closed position the catch engaged by the latch progressively increases a gripping force on a pipe.
  • fastening of the gripping system is integrated with the gripper such that it may be particularly convenient to operate compared to an equivalent fastening system which includes a removable locking member. Moreover, parts of the clasp fastening system are not susceptible to being dropped in a wellbore during assembly.
