Apparatus, system and method for pumping gaseous fluid

A reciprocating well pump assembly has a barrel and a piston reciprocally carried within the barrel between up stroke and down stroke positions. A travelling valve moves with the piston and has a closed position during the up stroke an open position during the down stroke. A relief port extends from a bore of the piston below the travelling valve into the barrel. A valve sleeve mounted around the body of the travelling valve is axially movable between a closed position, closing the tubular body relief port, and an open position, communicating well fluid in the barrel with the well fluid in the bore of the piston. When nearing the top of the stroke, the valve sleeve abuts a stop in the barrel. Continued upward movement of the piston causes the valve sleeve to open the relief port.

A well fluid submersible pump assembly includes a pump operatively coupled to a motor and a seal section located between the motor and the pump. The seal section has a single piece tubular housing with adapters secured to opposite ends of the housing. A shaft extends axially through the housing for driving the pump. An auxiliary seal carrier located in the housing has a central bore through which the shaft extends and has an outer diameter portion that seals to the bore of the housing. Opposed check valves in the seal carrier allow lubricant to flow from one side of the auxiliary carrier to an opposite side of the seal carrier in response to a selected pressure differential. A mechanical face seal mounts to the auxiliary seal carrier and seals around the shaft.

A well pump includes a plunger reciprocally carried within a barrel between up stroke and down stroke positions. A tubular linear actuator housing located below the barrel has a rotatable rotor. An array of rotor magnets is mounted to the rotor, directing rotor magnetic fields in an outward direction. A cage is fixed against rotation relative to the housing and carried within the housing for axial movement relative to the rotor and the housing. The cage has a cylindrical inner sidewall surrounding the outer sidewall of the rotor. An array of cage magnets is mounted to the inner sidewall of the cage. The cage magnets direct cage magnetic fields in an inward direction relative to the axis. The cage and rotor magnetic fields interact such rotation of the rotor causes axial movement of the cage. A motor rotates the rotor.

An apparatus, system and method for pumping gaseous fluid are described. The centrifugal pump of the invention homogenizes at least a portion of the gas and liquid contained in produced well fluid thereby improving the efficiency of the pump in electric submersible pump (ESP) applications and decreasing the downtime of the ESP system. The impeller of the invention comprises an increased inlet area. The centrifugal pump of the invention comprises a single shroud located on the bottom side of an impeller, an increased inlet area of the impeller and an increased clearance gap between the impeller and a diffuser. One or more truncated vanes extend substantially upstream from the single shroud, wherein each truncated vane sits at a mid-pitch location between untruncated vanes starting from the bottom side of the impeller.

An electrical submersible pump assembly includes a centrifugal pump having impellers and diffusers. A thrust runner is coupled to a motor shaft for rotation along with the impellers. The runner receives thrust from at least one of the impellers and transfers the thrust to a bushing non rotatably mounted in one of the diffusers. The bushing has a thrust transferring end adjacent a thrust receiving shoulder in the diffuser. The bushing is axially movable in the receptacle. An annular spring located between the thrust receiving shoulder in the receptacle and the thrust transferring end of the bushing urges the bushing away from the thrust receiving shoulder.

Compliant abrasion resistant bearings for a submersible well pump

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.

Connection assembly for through tubing conveyed submersible pumps

An electric motor of an electric submersible pump is electrically isolated from a power conduit for diagnostic testing of the power conduit and wet connection components in place within a wellbore. The electric motor is electrically connected to the power conduit through a wet connection assembly having motor leads in electrical connection with a transfer contact and a receptacle assembly disposed on a tubing string having a supply contact electrically connected to the power conduit. Electric power flows through the power conduit, through the supply contact, through the transfer contact, and through the motor leads to the motor. The supply contact and the transfer contact are separated by a sliding sleeve that hydraulically inserts between the contacts, insulating the transfer contact and grounding the supply contact for testing. The contacts may also be separated by a relative rotation of the assemblies that grounds the supply contact for testing.
