Abstract: An electrical submersible pump assembly has a seal section housing for coupling between a motor and a pump of the assembly. A bladder has an opening sized to slide over an adapter in the seal section housing. A clamp ring is formed of a shape memory alloy selected to create an expanded condition inner diameter when at a room temperature, enabling the clamp ring to be inserted over the bladder opening during assembly. When heated to a selected elevated temperature, the clamp ring contracts and tightly secures the opening around the adapter. The shape memory alloy of the clamp ring also causes the contracted condition inner diameter to expand when chilled to a selected low temperature.

Abstract: A fixture has a body that connects to a motor, the body having a bore. The body has a piston in the bore, separating the bore into a pressure chamber and a lubricant chamber in fluid communication with lubricant in the motor. A technician applies pressure to the pressure chamber, which causes the piston to increase pressure of the lubricant in the lubricant chamber and in the motor. The technician monitors a distance of movement of the piston, indicating a presence of residual air in the lubricant. If the movement meets a amount, the technician applies a vacuum to the lubricant chamber and bleeds out residual air from the lubricant in the motor.

Abstract: A seal section of a submersible well pump assembly has an expandable and contractible bag surrounded by a pressure equalizing chamber. A motor lubricant communication path communicates motor lubricant the bag interior. A well fluid port admits well fluid into the pressure equalizing chamber. A gas vent passage leads from the pressure equalizing chamber to the exterior of the enclosure. At least one membrane in the gas vent passage allows gas contained in the well fluid in the pressure equalizing chamber to vent. The membrane blocks liquid from flowing through the gas vent passage into and out of the pressure equalizing chamber.

Abstract: A seal section for use in a downhole submersible pumping system includes a lower chamber, an upper chamber and an intermediate guide section between the lower chamber and the upper chamber. The lower chamber includes a seal bag assembly that has a seal bag containing motor oil and an exterior space around the seal bag that contains high density oil that is denser than the motor oil. The upper chamber includes a volume of the high density oil at the bottom of the upper chamber and a gravity trap connected to the exterior space through an intermediate passage in the intermediate guide section. The gravity trap includes an opening submerged in the volume of high density oil in the upper chamber.
