What is hydraulic piston pump oil production

Hydraulic piston pump oil production is a hydraulic drive rod pumping equipment. Ground power pump through the tubing to the power transmission fluid downhole drive and reversing valve, thus driving the pump pumping work. Applications: Heavy oil wells and high waxy wells, deep wells and directional wells, and high efficiency. System composition and working principle of the pump: The underground part is the main unit of hydraulic piston pump, and its oil-hydraulic motive, hydraulic piston pump and slide valve control mechanism composed of three parts, plays a major role in oil pumping; the ground part of the ground pump , Various control valves and power fluid handling equipment, etc., serving as a supply and treatment fluid. The middle part consists of a central power tubing and a dedicated access for return of crude oil and working power to the ground. The new large displacement double-acting hydraulic piston pump in order to adapt to the gradual rise of oil wells in oilfield development and oil production.
