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.

摘要： The pump can be utilized in gassy oil wells to prevent gas slugs from locking the electrical submersible pump. A shroud assembly is provided with a bottom that can be fixed to the top of a seal section connected to the top of a motor. Additional lengths of shroud can be added as the shroud assembly is lowered into the well. The electrical submersible pump can then lowered into the shroud and supported from a production tubing string. A hanger can then be attached to the production tubing string to carry the weight of the shroud assembly, motor, and seal section.

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： An electrical submersible well pump assembly having a progressing cavity pump, a pump motor, a flex shaft connecting the pump motor to the pump, and a gas/liquid separator on the inlet to the pump. An inner and outer housing circumscribe a portion of the flex shaft, each having fluid inlets. The fluid inlets on the outer housing are above the inner housing inlets and an annulus is formed between the inner and outer housing. Wellbore fluid enters the assembly through the outer housing inlets, flows downward through the annulus, and into the inner housing inlets. Gas separates from the liquid as the fluid flows downward from the outer housing inlets to the inner housing inlets.

摘要： A well pumping system has a downhole rotary pump that drives a downhole reciprocating pump. The reciprocating pump is an intensifier, having a primary piston and a secondary piston of lesser diameter. A sequencing valve connects between the discharge of the rotary pump and the primary cylinder for alternately supplying well fluid from the rotary pump to the primary piston to stroke the primary and secondary pistons. The secondary piston pumps well fluid to the surface.

摘要： A well pump has a riser gas separator for removing large slugs of gas prior to reentry into the pump. The riser extends upward from a barrier that is located in the well. The riser has an inlet that is located above an effective intake of the pump. Well fluid must turn to flow down to the pump, with gas separating by gravity flowing upward while the liquid flows downward. The downhole assembly has various configurations to assure that fluid flows past the motor for cooling.
