Abstract
The utility model relates to the technical field of oil extraction, providing a twin pipe type rod free hydraulic oil pumping system used in the oil pumping of oil fields or wells. The utility model consists essentially of a separator, a safety valve, an oil gas regulating valve, a filter, a high pressure triple plunger pump, a one way valve, a bladder type hydropneumatic accumulator, a mechanical reversing slide valve device, a throttle valve, a hydraulic hoisting mechanism, a pull rod and a defueling pump. The utility model adopts the high pressure power fluid provided by the high pressure triple plunger pump to drive the hydraulic hoisting mechanism to drive the defuelding pump for ascending for the realization of liquid absorption. In case of a low pressure, a defueling pump plunger descends to realize liquid exhaustion under the action of the counter weight. As sucker rod is absent, the camber wear of oil pumping rod pipe of inclined shafts when a beam pumping system is used may be eradicated, thus, the system may be widely applied to the oil pumping of inclined shafts of oil fields. Besides, the utility model also has the advantages of small volume, low cost and simple structure and therefore is of a great value of popularization and use.
