摘要： A submersible pumping system for use downhole, wherein the system includes a first pump, a second pump, a recirculation coupling between the first and second pumps, and a recirculation line for directing cooling flow across the pump motor. The pumps and coupling are independent modular items connected together. Optionally, a multi-stage pump may be retrofitted with the coupling for creating a cooling flow.

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 pump assembly has a pump discharge head with an integrally formed pump discharge pressure port. The discharge head is mounted directly to the pump and couples the pump to production tubing. A static pressure port extends directly through the side wall of the discharge head. The pressure port includes a tubing connector for hydraulic tubing to run down to the gauge. Inside the discharge head, a flow limiter is located in the pressure port to stop the loss of fluid if there is a break in the tubing connector or hydraulic line. Alternatively, the discharge head may incorporate a venturi or other pressure drop structure to allow the fluid flow to be measured via a pressure drop across an orifice. The venturi may be configured as an insert to permit it to be replaced after it has become worn by abrasive flow.

摘要： A combined gas separator and pump in an electrical submersible pump assembly is disclosed. An integral discharge connector threadingly couples the gas separator and pump. The connector contains discharge ports for the discharge of the separated gas. The pump shaft and gas separator shaft are also coupled. Alternatively, a single pump shaft extends from the pump into the gas separator. In another alternative, the gas separator is completely integrated into the pump housing. The pump is modified by removing the intake of the pump and a sufficient number of pump stages to accommodate the gas separator components. A diverter tube is located in the pump housing and the pump housing is modified to include gas exit ports. All of the gas separator components are located in the modified pump housing, and the original pump intake is reattached at its original location.
