    摘要: A device and method can detect, and also break, an occurrence of gas lock in an electrical submersible pump assembly in a well bore based upon surface or downhole data without the need for operator intervention. To detect an occurrence of gas lock, an instantaneous value is monitored using a sensor. Then a controller compares the instantaneous value to a threshold value over a predetermined duration to thereby detect the occurrence of gas lock in the electrical submersible pump assembly. Sensors can include, for example, a differential pressure gauge, a pressure gage located in a pump stage located toward the inlet, a fluid temperature sensor located toward the discharge, a free gas detector located near the pump discharge, an electrical resistivity gage, a flow meter located within surface production tubing, and a vibration sensor attached to a tubing string to measure a vibration signature.

    摘要: An intake assembly for a well pump restricts gas entry into the pump when the pump is located in a horizontal section of the well bore. The restrictor is located within a tubular intake housing. The intake housing has apertures for receiving the flow of well fluid. The apertures are spaced circumferentially around the housing. Once installed in the well, some of the apertures will be at higher elevations than others. The restrictor partially blocks at least one of the higher elevation apertures and opens at least one of the lower elevation apertures. The gas will be at the higher elevations, thus it is restricted from flowing in through the higher elevation aperture while the liquid freely flows into the lower elevation aperture. The restrictor may be of a buoyant material to float upward in the well fluid. The restrictor may also be open in response to contact with the casing wall.

    摘要: A submersible centrifugal pump is disclosed. It includes a housing with a linear stack of axially mounted pumping units therein. Each unit constructed as a module with at least a first and a second impeller mounted to a central shaft. A diffuser forms an outer casing which is provided for each impeller. A thrust bearing, lubricated and cooled by the fluid being pumped is supported from and to the outer casing and is arranged to receive axial force from the upstream impellers in each modular unit. A plurality of impellers and diffusers can form a single modular unit.

    摘要: A downhole well pumping assembly has a shroud with an upper section and a lower section sealed from one another. A submersible pump and a gas separator are housed within the upper section of the shroud. The gas separator has a liquid outlet in fluid communication with an intake of the pump, and a gas outlet in fluid communication with the gas outlet in the shroud. A motor is housed within the lower section of the shroud, the motor being coupled to the gas separator for rotating the gas separator and the pump. A well fluid lower inlet is in the shroud below the motor and a well fluid lower outlet is in the shroud above the motor.

    摘要: An electric submersible pump ESP is run in to a desired subterranean location with a packer attached. Once at the desired location the packer is set either using the ESP or some other source of force or pressure. After the ESP has completed the task and needs to be removed, the packer stays set and the ESP releases from it. Removal of the ESP assembly allows a valve in the packer mandrel to close to isolate the zone from which the ESP had been pumping. The ESP can be run in on coiled tubing or rigid tubing or wireline.

    摘要: A gas separator has a separator member that rotates with a shaft for separation of fluid components. A flow divider directs more dense fluid to the pump and less dense fluid into an annulus surrounding the pump. An impeller is located within the flow divider for urging fluid out of a downstream gas exit port. A single large gas exit port is used and may be combined with use of a single large fluid inlet. An auger may be located within the rotary separator member. Holes may be located in the sidewall of the rotary member or chamber. The holes are preferably located in a helical pattern above and adjacent the flights of the auger or are in vertical columns adjacent the baffles. The chamber may have a cylindrical or tapered profile. Alternatively, a series of sub-chambers may be used, each having a smaller radius than the preceding, upstream sub-chambers.
