RECIPROCATING ELECTRICAL SUBMERSIBLE WELL PUMP

摘要

A downhole pump system includes a magnetically operated rotary to linear motion converter coupled at a rotary input to a drive source. A reciprocating action positive displacement pump having a reciprocating input thereto is coupled to a linear motion output of the magnetically operated rotary to linear motion converter. An intake of the pump is in fluid communication with a wellbore region and a discharge of the pump is in fluid communication with a well conduit extending to Earth's surface.
