ABSTRACT:
A hydraulically operated downhole pump that is connected to or disposed in a string of tubing, and when operated by pressurized oil from the ground surface, is capable of discharging production fluid, gas, and pressurized oil from the well either separately or in desired combinations thereof. The pump includes an elongate housing preferably of such transverse cross section as to be longitudinally movable through a tubing string, with the pump including universal joint connected upper and lower helical screws that rotate in slidable sealing contact with upper and lower double threaded resilient stator blocks secured to the interior of the housing. As pressurized oil is discharged into the upper end of the housing the upper helical screw and associated stator act as a motor to drive the lower helical screw relative to the lower stator block. As the lower helical screw rotates relative to the lower stator block, the lower helical screw acts as a pump to discharge production fluid from the well upwardly therein either separately or in combination with the pressurized oil depending on the components associated with the pump.
