Abstract

The embodiment of the invention provides an oil production device and system. The oil production device comprises an oil production pump, an oil pumping plunger, a flexible polish rod, a packing box,a steering bracket and a flexible polish rod winding and unwinding device. The oil production pump is mounted in a downhole oil pipe; the oil pumping plunger is arranged inside the oil production pumpand used for delivering downhole crude oil; a steering pulley is arranged on the steering bracket; one end of the flexible polish rod is connected with the oil pumping plunger, and the other end of the flexible polish rod is connected with the flexible polish rod winding and unwinding device through the packing box and the steering pulley; and the flexible polish rod and the oil pumping plunger are driven to move in the oil production pump in a reciprocating mode under driving of the flexible polish rod winding and unwinding device. Thus, the oil production device has all the advantages of aplunger-pump-type oil pumping unit; and the stroke of the oil pumping plunger is determined by the length of the oil production pump, the length of the flexible polish rod and the travel of the winding and unwinding device, so that the stroke of the oil pumping plunger far exceeds the long stroke of a traditional walking-beam-type oil pumping unit quite easily, and thus the characteristics of lesstimes of stroke, less stroke loss and high pump efficiency are further achieved.

Description

technical field [0001] The invention relates to the technical field of oil recovery, in particular to an oil recovery equipment and an oil recovery system. Background technique [0002] At present, the traditional plunger pump type oil production process has the problems of high stroke frequency and low equipment safety, which leads to the shortened life of the sucker rod, increased frequency of pump maintenance, and increases the cost of the oil production process. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an oil production equipment and oil production system, which realizes flexible start and stop, has the characteristics of small impact, low stroke frequency, small stroke loss and high pump efficiency, and effectively saves electric energy , and improves the safety of the equipment, greatly prolongs the life of the equipment, can greatly reduce the number ...
