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

摘要： A submersible pump gas separator for a well pump has a housing with a rotatable shaft. A separating section in the housing separates heavier well fluid components into an area radially outward from the lighter components. A crossover member rotates with the shaft. The crossover member has a helical liquid passage having an inlet in fluid communication with the separating section for receiving the heavier components and an outlet in fluid communication with a liquid outlet of the housing. The crossover has a gas passage having an inlet in fluid communication with the separating section for receiving the lighter components and an outlet in fluid communication with a gas outlet of the housing.

摘要： An electrical submersible pump (ESP) having tubing for recirculating fluid below the motor of the ESP for cooling purposes. By recirculating fluid below the motor, an ESP can then be placed below the perforations in a well casing, thereby taking advantage of gas separation from the fluid before the fluid enters the pump intake. Three embodiments are disclosed: a fluid tap in the production pump housing to which tubing is connected to recirculate the fluid; a recirculation pump that shares an intake with the production pump wherein the recirculation pump is used to recirculate the fluid; and a recirculation pump and a production pump that each have a separate intake wherein the recirculation pump is used to recirculate the fluid.
