ABSTRACT:
A new and improved control system for monitoring and controlling the operation of a downhole linear d.c. motor-pump assembly and a method of using it for producing a sufficient reciprocating pumping action to lift well fluid through the producing tubing of a well to the ground surface. The system includes a surface monitoring station that is in radio communication with a plurality of remote downhole motor-pump assemblies. Each motor-pump assembly has a surface motor controller, a downhole motor-pump cartridge unit that is adapted to be received in a downhole cartridge sleeve assembly that maintains the cartridge unit in a stationary position for pumping purposes. The motor-pump cartridge unit may be raised or lowered by a control cable within the production tubing for helping to facilitate the repair or replacement of the motor-pump cartridge unit. The motor-pump assembly also includes a plurality of sensors for monitoring the conditions of the well downhole as well as the efficiency of the motor-pump cartridge unit.
