摘要： Disclosed are methods and devices for testing downhole connector electrical systems and cable integrity during installation of a permanent completion, including a customized retrievable plug arm assembly connectable to the completion during RIH, the tool mimicking a retrievable ESP, but without motor, and can be employed with or without pressure isolation. Another method employs a slidable starpoint located within the downhole wet mate connector of the completion to provide continuous electrical contact between the phases when no retrievable assembly is in place. When a retrievable assembly is later put in place, the slidable starpoint is moved into a second position that no longer provides electrical contact between the phases. Another method uses fusible links installed between two conductors within the downhole electrical connector system of the completion to provide similar electrical contact between phases, the fusible link configured to melt away once motor current is sent through the conductors.

摘要： A downhole electrical wet connector comprising a plug which is slidingly inserted into a socket, the socket comprising a series of wiper seals spaced apart by separation zones, each zone being individually supplied with dielectric fluid from a separate reservoir. A retractable insert is arranged in the socket and displaced by the plug during connection. The fluid pressure in each zone is individually regulated relative to ambient wellbore pressure and the pressure in adjacent zones and optionally equalized to minimize loss of fluid.

摘要： A system and method for hydraulic isolation of a downhole powered system. The system and method include a sliding sleeve, venting assemblies with venting ports, and check valves associated with a vent body, and an isolation sleeve, isolation valve, and integral packer for controlling fluid flow through the motor and pump assembly of the powered system. Also disclosed is a wet connect mandrel modified to receive the isolation sleeve, the isolation sleeve preferably capable of permitting the passage of tools therethrough and capable of preventing fluid through the inlet of the mandrel. The mandrel may also be outfitted with a built-in sliding sleeve. The sleeves, valves and packer can be actuated mechanically, hydraulically or electrically. Electrical actuation can be facilitated using the power from an adjacent wet connect mandrel.

摘要： A system and a method for removing a portion of an electric submersible pump power cable conduit housing are provided. The method may include cutting a conduit housing of the conduit, sliding the cut conduit housing off the conduit, and squaring an end surface of remaining conduit housing. The cutting of the conduit housing is not a through cut and the sliding of the cut conduit housing off of the cut conduit is performed with a conduit housing spreader. The system may include a conduit housing cutter for cutting partially through the conduit housing of the conduit and a conduit housing spreader for pulling the portion of the conduit housing apart from a remaining conduit housing. In addition, the system may include a squaring tool to square an end surface of the remaining conduit housing relative to an axis of the conduit.

摘要： A stress cone for reducing electrical stresses is disclosed for use on terminated ends of tubing encapsulated power cable used in surface applications in a subsurface well power system employing electric submersible pumps (ESPs). The stress cone comprises an annular section about a longitudinal axis for receiving a terminated end of the TEPC in its first end and for abutting the terminated metal TEPC end against a metal shoulder at its second end therein, and an insulation chamber axially aligned with and connected to the annular section. The chamber comprises a metal interior surface symmetrical about the axis. The insulated TEPC core (without outer metal sheath) passes through the insulation chamber along the axis and then exits. The ID of the TEPC metal sheath and the inside metal surface of the chamber form a smooth ground plane transition surface. Insulation material surrounds the TEPC insulation layer within the insulation chamber.
