摘要： Systems and methods for providing artificial lift to wellbore fluids include a pump located within a wellbore. A motor is located uphole of the pump and a protector assembly is located between the pump and the motor. A downhole packer is located within the wellbore downhole of the pump. A sand diverter is located downhole of the pump and has a flow port assembly located uphole of the downhole packer, the sand diverter having a diverter inner bore in fluid communication with the wellbore downhole of the downhole packer. The flow port assembly has an inner sleeve that is moveable between an open position where an inner sleeve port assembly is aligned with an outer sleeve port assembly of an outer sleeve, and a closed position where the inner sleeve port assembly is unaligned with the outer sleeve port assembly.

摘要： An invention relates to a field of oil production, in particular, to installations with displacement pumps driven by submersible linear electric motors, and can be used for production of stratum fluids from a marginal well stock from great depths. The described technical solution implementation ensures unification of a design with simultaneous increase in a manufacturing processability by means of involving of easily removable interoperable modules for its manufacture. Also a described embodiment contributes to decrease in a pump unit dimensions. According to the described embodiment of the invention a telemetry system performance provides an increase in a level of protection from a high-voltage interference with implementation of a hardware-software mode of a surface control unit for checking an insulation. Providing that an arrangement of the described design ensures a reduction in dynamic loads on elements of an electrical motor design and contributes to increase in its operating resource.

摘要： A method of operating a submersible pumping system includes the steps of placing the pumping system in a normal mode of operation and then detecting the possible presence of a gas slug in proximity to the pumping system by measuring a decrease in the load on the motor. Once the possibility of a gas slug has been detected, the method continues by placing the pumping system in a reduced speed cycle. The pumping system is kept in the reduced speed cycle until the absence of a gas slug in proximity to the pumping system is detected by evaluating two independent conditions within the pumping system.

摘要： An inline monitoring package for a submersible pumping system includes a housing having a first end for connection to a motor, a pump or a seal section of the pumping system, and a second end for connection to the motor, the pump or the seal section. The housing is disposed between any two of the pump, the motor and the seal section. A shaft transmits rotation from the motor to the pump. The housing comprises a chassis having a through bore and an end plug at each longitudinal end. The through bore has a diameter selected to enable free passage of the shaft and fluid associated with the shaft. The end plugs sealingly engage an interior wall of the housing so as to define a sealed chamber inside the housing and external to the chassis between the end plugs. At least one electronic component is disposed in the sealed chamber.

摘要： Some implementations include a method for controlling a computer system configured to detect scaling and/or plugging of an electric submersible pump (ESP) deployed in a wellbore. The method may include determining, based on a measurement of pressure in the wellbore, a required total dynamic head (RTDH) for the ESP while the ESP is operating in the wellbore. The method also may include determining, based on information from one or more sensors in the ESP, a produced total dynamic head (PTDH) for the ESP while the ESP is operating in the wellbore. The method also may include detecting scaling status or plugging status of the ESP based on the RTDH and the PTDH.
