摘要： A connection module is disclosed for a submergible pumping system of the type including a submergible electric motor and a pump drivingly coupled to the motor. The system may also include additional components such as a fluid separators, an injection pump, and so forth. The connection module includes a body through which a fluid passage is formed. A recess is formed in the body for receiving a cable for transmitting power to the submergible electric motor. The fluid passage transfers fluid within the pumping system, such as by means of shrouds disposed around the system components. The connection module also includes an electrical connector for completing current carrying paths between a supply cable and the motor. The connection module may thus serve as the motor head in which the electrical connections are made, but through which fluid is channeled to system components. The module is particularly useful for connecting a shroud around the motor, while accommodating the power cable entry at an end of the motor.

摘要： A fluid separation system is provided for separating wellbore fluids into production fluids and non-production fluids. The system includes a separator adapted for transmitting mechanical power between a drive motor and at least one pump. The separator includes one or more separation units, such as hydrocyclone separators. A drive train traversing the separator is interfaced with drive elements, such as a submergible electric motor, and driven elements such as an injection or production pump. Wellbore fluids are channeled through the separator in either a push-through or pull-through manner. Production fluids are then transferred from the separator to the production pump for removal from the well. Non-production fluids are transmitted from the separator either to the injection pump for reinjection into a subterranean discharge zone, or directly into the discharge zone from the separator. The drive train elements traversing the separator are supported by antifriction bearings in interface plates on either end of the separator. The ability to transmit mechanical power through the separator facilitates assembly of pumping system components in various configurations as well as piping fluid communication paths between the pumping system components.

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 method and related apparatus for the retrieval of a rotary pump from a wellbore while leaving the pump's drive mechanism within the wellbore, comprises lowering a latch mechanism into a wellbore by a cable or coiled tubing and connecting the latch mechanism to the rotary pump suspended within the wellbore. Holding mechanisms, which removably connect the rotary pump to the pump's drive mechanism, are disengaged by pulling of the cable or coiled tubing, or by the application of hydraulic pressure. The latch mechanism and the pump are then retrieved from the wellbore, while the drive mechanism remains suspended within the wellbore.
