潜油电动离心泵(简称电潜泵)是用于井下抽油的一种多级离心泵。它与油管一起下入井内,由专用电缆把电能从地面输入井下电机,由电机带动运转,将井下原油举升到地面。
Submersible electric centrifugal pump (referred to as electric submersible pump) is a multi-stage centrifugal pump for underground pumping. It goes down into the well together with the tubing, and the electrical energy is input into the downhole motor from the ground by the special cable. The motor drives the crude oil to lift to the ground.
