    摘要: A motor protector for use in protecting an electric motor in a subterranean environment. The motor protector utilizes a dual, flexible bladder system. One of the expandable bladders provides for the expansion and contraction of motor oil. The other expandable bladder contains a supply of neutralizing solution. The bladder filled with neutralizing solution cooperates with the bladder filled with motor oil to maintain the expandable bladder bathed in neutralizing solution. This prevents migration of corrosive agents into the motor oil.

    摘要: A system for separating gas from a wellbore fluid as it is produced to the surface. The system includes a progressing cavity pump, a submergible electric motor and a fluid intake. The submergible electric motor is connected to the progressing cavity pump to drive the pump and draw wellbore fluid through the fluid intake. The fluid intake includes a hollow interior defined by a thick-walled section. Additionally, the fluid intake includes a plurality of fluid passageways extending through the thick-walled section. The passageways are oriented to create a reversal in fluid flow, and thus a release of gas, as the fluid is draw into the fluid intake.

    摘要: A rotary gas separator for use with a progressive cavity pump which includes a separation housing having an internal separation chamber with a bladed separator rotatably mounted therewithin for separating introduced fluid into a gas constituent and a liquid constituent. Coupling mechanisms are mounted on a first end of the bladed separator for connection to a rotor of a progressive cavity pump, and for permitting limited longitudinal movement and limited transverse movement between the bladed separator and the rotor to prevent bearing failure within the drive train of the pump.
