    摘要: A gas separator having an improved flowpath for lighter fluids having a higher concentration of gas decreases total pumping head for an ESP assembly. The ESP assembly includes a rotary primary pump, a motor coupled to the primary pump for driving the pump, a seal assembly between the primary pump and the motor, and a gas separator between the seal assembly and the primary pump. An outlet of the gas separator feeds an intake of the primary pump, and a rotating shaft operationally couples the primary pump to the motor and passes through the seal assembly and the gas separator. The gas separator contains a venting portion, and a diverter positioned within the venting portion having diverter guide vanes formed in a flowpath of the lighter fluid for aiding in a directional change of fluid momentum. A slinger is positioned within the diverter for impelling fluid through the venting port.

    摘要: A two-phase, homogenizing or mixing stage for a centrifugal pump assembly homogenizes the fluids being circulated therethrough. The mixing stage produces high shut-in head pressure and a very high maximum flow rate. The mixing stage has a diffuser with fixed diffuser vanes that extend radially or tangentially at acute angles. The vanes may be curved in both the axial and radial directions to force fluids impinging thereon to have a radially inward component to create turbulence. The turbulence mixes and homogenizes the gas and liquid fluids to improve the overall performance of centrifugal pump assemblies that operate in two-phase fluids. The mixing stage also has an impeller adjacent the diffuser. The impeller vanes likewise extend radially and tangentially therefrom at acute angles and may be curved.

    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. An extraction tube has an upper end above the shroud within the upper portion of the caisson and a lower end connected to a jet pump. The extraction tube causes gas that separates from the liquid and collects in the upper portion of the caisson to be drawn into the jet pump and mixed with the liquid as the liquid is being pumped.

    摘要: A progressing cavity pump is located within a well and has a gas separator for separating gas before reaching the pump. The pump has a rotor that is driven by a string of rods extending to the surface. A drive shaft for the gas separator is coupled to the rotor during pumping operation both for axial as well as rotational movement. The rotor assembly, when lowered through the tubing, stabs into engagement with the drive shaft of the gas separator in one version. In another version, the gas separator drive shaft is lowered through the tubing with the rotor and stabs into a hub sleeve in the gas separator.

    摘要: A submersible well pump assembly has a gas separator that separates gas prior to entering into the pump. A shroud encloses a portion of the pump assembly, including the gas separator. The gas separator has gas discharge tubes that extend from it out through the shroud. The gas discharge tubes are tangentially aligned to create a vortex on the exterior of the shroud.

    摘要: A centrifugal pump pumps well fluid with a high gaseous content by conditioning the well fluid with a conditioning impeller and conditioning diffuser design for use with gaseous well fluid. The conditioning impellers have vanes that are curved with a leading edge that is rotationally forward and axially below, or upstream, of a trailing edge. The outer end of the leading edge is rotationally forward of the inner end of the leading edge, which forces the well fluid radially inward and mixes the gas and liquids in the well fluid. The conditioning diffusers have blades that are curved with a leading edge that is rotationarily rearward and axially below a trailing edge. The blades are portions of a sphere, with a concaved side receiving well fluid from the conditioning impellers. The spherical shape forces the well fluid radially inward and axially upward.

    摘要: An electrical submersible pump (ESP) having a sleeve coupled to the shaft that rotates as the shaft rotates. The sleeve can be a base portion of a pump impeller, a journal bearing, or a bushing. A drive collar mounts around the shaft and has an end with a portion that projects past an end of the sleeve profiled to correspond with the shape of the projecting portion. As the shaft rotates the drive collar the projecting portion of the drive collar pushes against the profiled end of the sleeve to rotate the sleeve. The projecting portion can be a wedge shaped tab on the drive collar, or an angular segment of the drive collar extending axially past the remaining segments. The profiled end of the sleeve can include a recess formed to receive the tab and can have an angular segment corresponding to that on the drive collar.
