摘要： A system for producing wellbore fluids. The system includes a pumping system deployable into tubing disposed in a wellbore, the pumping system includes a pump, a pump motor, a reservoir for containing purging fluid, and conductors in electrical communication with the pump motor. Electrical supply contacts are provided in the tubing and are connected to a downhole electrical power supply via a power cable extending along the tubing length from the surface. The conductors are engageable with the electrical supply contacts when the pumping system is landed within the tubing. Purging fluid in the reservoir can be flowed between the conductors and the supply contacts to remove conductive fluid prior to engaging the conductors and supply contacts. The conductors are selectively extended from a retracted position in the pumping system. In an alternative embodiment, the electrical supply contacts are provided at locations along the length of the tubing.

摘要： An electrical submersible pumping (ESP) system for use in a wellbore having a pressure equalization system that employs modules with a bellows. The bellows axially expands and contracts in response to pressure fluctuations encountered in the wellbore. The modules are attachable in series on a lower end of a motor of the ESP to form the string, where the string can range from a single module to a multiplicity of modules, depending on the application. The bellows has a conduit axially inserted through the bellows that includes an umbilical and has an end in pressure communication with the motor.

摘要： A well conveyance system couples to an uphole end of an artificial lift system and operates to push the artificial lift system through a tubing string for deployment in a wellbore. The well conveyance system includes a wellbore tractor adapted to push the artificial lift system through the tubing string and a swab cup assembly having a swab cup and a perforated nipple extending therethrough. The perforated nipple includes a nipple passage allowing for fluid flow from an area downhole from the swab cup to an area uphole from the swab cup when the wellbore tractor operates. A valve selectively blocks the perforated nipple to permit a hydraulic pressure to be applied to the tubing string uphole of the swab cup, exerting a downhole force on the swab cup to aid in deployment of the artificial lift system.

摘要： A latching mechanism for selectively disengaging an upper pump from a motor in an ESP. The latching mechanism comprises barbs formed on an upper end of an upper shaft that are engaged by a tool to lift the upper shaft until a lower end of the upper shaft disengages from an upper end of a motor shaft. When the upper pump is disengaged from the motor shaft, only a lower pump is driven by the motor and flow of well fluid is circulated past the disengaged upper pump via a bypass line. The upper pump shaft may reengage the motor shaft if additional lift is required.

摘要： An electrical submersible pumping (ESP) system for use in a wellbore that can be assembled in the wellbore. Upper and lower pump tandems are fitted with connectors that align the tandems when coupled in the wellbore. The connectors on the lower tandems have bores with enlarged openings on upward facing surfaces. Downward pointing pins are on lower facing surfaces of the connectors on the upper tandems. The cross sectional area of each bore decreases with distance away from the openings, so that as the pins insert into the bores the pins move along a helical path that in turn rotates the upper tandem into a designated azimuth and into alignment with the lower tandem. Properly aligning the upper and lower tandems couples respective drive and driven shafts in the tandems as the upper tandem lands on the lower tandem.

摘要： A submersible electric motor has feature to enhance thermal conductivity from the motor interior to the exterior. The motor has a cylindrical housing and a stator rigidly mounted within housing. A rotatable rotor is located within the stator. A gap formed between the stator's outer diameter and the inner wall of the housing is filled with a high thermal conductivity material to improve heat transfer from the motor. The remaining portion of the housing may be filled with a dielectric lubricant that has lesser thermal conductivity than the high thermal conductivity material.

摘要： The pump can be utilized in gassy oil wells to prevent gas slugs from locking the electrical submersible pump. A shroud assembly is provided with a bottom that can be fixed to the top of a seal section connected to the top of a motor. Additional lengths of shroud can be added as the shroud assembly is lowered into the well. The electrical submersible pump can then lowered into the shroud and supported from a production tubing string. A hanger can then be attached to the production tubing string to carry the weight of the shroud assembly, motor, and seal section.
