Embodiment Construction
[0017] Such as Figure 1-Figure 2 As shown, the high-efficiency separate recovery double-acting oil well pump includes a pump barrel assembly and a plunger assembly arranged in the pump barrel assembly. The pump barrel assembly has a double-layer structure, and the lower end of the pump barrel assembly is provided with two oil inlets The two oil inlets communicate with the inner layer and the outer layer of the pump barrel assembly respectively, and a downstroke sealing device is arranged between the pump barrel assembly and the upper end of the plunger assembly.
[0018] The plunger assembly is arranged in the inner structure of the pump cylinder assembly.
[0019] The pump barrel assembly includes an upper collar 15, a bridge pipe 11 and a double-way joint 7 connected in sequence. The lower oil inlet of the double-way joint 7 is provided with a lower fixed valve 6, and the side oil inlet of the double-way joint 7 There is an upper fixed valve 8 connected to it, and a lower ...

The invention relates to an oil-well pump, in particular to an efficient separated mining double-acting oil-well pump which comprises a pump barrel assembly and a plunger piston assembly arranged in the pump barrel assembly; the pump barrel assembly is a double-layer structure; two oil inlets are formed in the lower end of the pump barrel assembly; the two oil inlets separately communicate with the inner layer and the outer layer of the pump barrel assembly; and a down stroke sealing device is arranged between the pump barrel assembly and the upper end of the plunger piston assembly. According to the efficient separated mining double-acting oil-well pump, the pump barrel assembly with the double-layer structure is adopted, two oil inlets are formed in the lower end of the pump barrel assembly, and the down stroke sealing device is arranged between the pump barrel assembly and the upper end of the plunger piston assembly, so that an oil extraction process and an oil swabbing process can be completed twice in one reciprocating stroke, and displacement of the pump is effectively improved; when fluid supply of an oil well is sufficient, efficiency of an oil-well system is effectively improved, so that energy saving and consumption reducing be realized, and the oil-field yield can reach the standards.
Description
technical field [0001] The invention relates to an oil well pump, in particular to a high-efficiency separate recovery double-acting oil well pump. Background technique [0002] Many oilfields in my country have entered the development stage of high water cut period. Since the displacement of existing oil well pumps cannot meet the requirements, various oilfields have widely used electric pumps for production to increase and stabilize crude oil production. However, electric pumps have a large one-time investment and accidents. The problems of high efficiency, high maintenance review and operation cost are not suitable for the purpose of saving energy and reducing consumption in oil fields and improving the economic benefits of single wells. Contents of the invention [0003] The technical problem to be solved by the present invention is: the displacement of the current oil well pump cannot meet the requirements of the development stage of the high water cut period of the oi...
