Abstract

The invention discloses a jamming prevention oil field oil pump, in particular to a jamming prevention oil field oil pump provided with an upper scraping unchoking device. The problem that an oil pumpis jammed or halts is solved. According to the technical scheme of the jamming prevention oil field oil pump, on the structural basis of an existing common oil pump, the upper scraping unchoking device capable of scraping sand is arranged between an upper traveling ball cover and an upper traveling valve connector so that sand grains in crude oil above a plunger cannot enter the position betweenthe plunger and a pump barrel, the problems of jamming and halt, caused by deposited sand grains in the crude oil, of the oil pump are effectively and completely eradicated, the plunger and the pump barrel can be protected, the effect of prolonging the service life is achieved, and the purposes that less faults are caused, and the efficiency of oil extraction is improved are achieved.

Description

technical field [0001] The invention relates to an oil production equipment in an oil field, in particular to an anti-jamming oil pump in an oil field. Background technique [0002] The oil pump is a common oil pumping equipment for pumping the crude oil in the well to the ground. The existing oil pump mainly consists of an upper moving ball cover, an upper sealing ball, an upper sealing ball seat, an upper fixed valve joint, and an upper moving valve joint. , plunger, pump barrel, middle-swimming valve cover, middle sealing ball, middle sealing ball seat, sealing seat cover, middle fixed valve joint, lower fixed valve cover, lower sealing ball, lower sealing ball seat, lower fixed valve joint The oil pumping method is to lift the crude oil from a low place to a high place through the up and down movement of the plunger and pump the crude oil from the bottom of the well to the top of the well and out of the well, because the sand contained in the crude oil is easy to accumul...
