    摘要: A seafloor pump assembly is installed within a caisson that has an upper end for receiving a flow of fluid containing gas and liquid. The pump assembly is enclosed within a shroud that has an upper end that seals around the pump assembly and a lower end that is below the motor and is open. A separating device is connected to an upper end portion of the discharge pipe within the caisson. The separating device causes separation of gas from the flow containing gas and liquid to be enhanced prior to the flow reaching the operating liquid level in the caisson.

    摘要: A centrifugal submersible pump has wear resistant features to resist erosion due to sand laden fluid from a well. The pump has diffusers and impellers located within the housing. Each diffuser has a diffuser sleeve with a coaxial bore. The diffuser sleeve is of a material harder than the remaining portions of the sleeve. A hardened lower hub locates slidingly within each diffuser sleeve. The lower hub rotates with the shaft. Each impeller has an upper hub that locates above the lower hub and is also carried by the shaft for rotation with the shaft. The upper hub extends into the bore of the next upward diffuser sleeve. The lower hub is of a material harder than the upper hub and the vane section of the impeller.

    摘要: A method of operating an electrical submersible pumping system that includes realtime monitoring of the wellbore fluid and adjusting pump speed so the fluid entering the pump remains subcooled. The method can include adding sensors within the wellbore and digitally storing fluid data accessible by a pump controller. The pump speed can be increased or decreased by adjusting the frequency of the electrical power delivered to the pump motor.

    摘要: A gas compressor is employed downhole in a well for pressurizing formation gas. The gas compressor is driven by a downhole electrical motor. The downhole assembly also includes a pump. The pump might be located below the motor and driven by the same motor. In that event, the pump pumps liquid being produced by the formation downward to a liquid disposal formation. Also, the pump may pump the liquid to the surface, with the gas being delivered into a repressurizing zone.

    摘要: The operating characteristics and the nominal, best operating point of a multi-stage centrifugal pump are shifted to lower flow rates without loss of nominal head and without substantial loss of efficiency by machining or otherwise shortening the trailing edge of all or some of the stationary guide vanes of the diffusers between impeller stages. By so doing, a single pump size can be adapted to a range of flow requirements, as desired. Thus, it is possible to reduce the number of pump sizes manufactured, and yet supply the needs of customers.

    摘要: A submersible pumping system for use downhole, wherein the system includes a pump, an inlet section for receiving fluid, a pump motor, and a viscometer. Pumping system operating parameters are adjusted based on wellbore fluid viscosity measured by the viscometer. The viscometer can be disposed deep in the wellbore, adjacent the pump, seal, motor, at the pump intake or anywhere on the pumping system. The viscometer may be connected to a control system for controlling the pumping system in response to viscosity measurement and may include a sonic viscometer. A method of operating a downhole submersible pumping system is included that measures fluid viscosity in the wellbore during production operations. Pumping parameters can be adjusted based on the measured viscosity.

    摘要: A protection system for an artificial lift device including but not limited to electrical submersible pump (ESP) and an electrical submersible progressing cavity pup (ESPCP). The artificial lift device is suspended on a tubing string into a wellbore where the artificial lift device contacts well fluids. The artificial lift device is provided with a barrier such as an intake barrier or output barrier that deters an ingress of well fluids into the artificial lift device. As a result, the artificial lift device may remain idle and submerged within well fluids for an extended period of time without experiencing degradation of the artificial lift device internals. The intake barrier may include a plug, burst disk, dissolvable material, a selectively openable barrier such as a sleeve or a spring biased member or other member that is capable of providing a suitable barrier. The barrier may be removed once the artificial lift device is ready for operation. The artificial lift device may be filled with a protective fluid. An optional pressure sensor may be provided that is in communication with the interior of the backup unit for communicating with a compressor that may be activated to maintain a positive pressure within the artificial lift device to prevent well fluids from entering the unit. The protection system of the invention is desirable for protecting an idle artificial lift device, including when the artificial lift device is a backup unit in a multi-artificial lift device deployment.

    摘要: A method for producing gas from a well with low pressure involves running a bottom hole pressure test to graph a P-Q curve. The operator computes a frictional pressure drop due to friction of the gas flowing through the production tubing to the surface. A packer is set above perforations in the well. A screw pump is selected that has a capacity equal to the sum of the frictional pressure drop plus a desired wellhead pressure. The screw pump has a flow rate capacity determined from the P-Q curve. The operator may vary the frequency of a downhole motor to achieve the desired wellhead pressure.
