Introduction of Electrical Submersible Pump (ESP) for Oilfield (Oil / Aquifer Medium) Electric submersible pump system consists of submersible pump (with intake or separator), gas handler, protector/seal section, motor, power cable & motor lead extension, downhole gauge/sensor, which is suitable for oilfield oil production engineering. It is used to lift oil at the bottom of the well to the ground. It is a roadless oil production equipment, which has the advantages of large flow capacity with high head. It can be widely used in high water-cut wells, deep wells, directional wells and other oil wells. According to user needs, it can also be used for transporting the other aquifer medium, like deep well water which has high head requirement.
