Abstract

The invention relates to the technical field of oil field exploitation, and discloses an oil well pump used in an oil field, which includes an oil well, a pump barrel and an oil inlet chamber, the pump barrel is fixedly socketed with the oil well, and the top end of the oil inlet chamber is connected to the bottom of the pump barrel. End fixed connection. Through the setting of the spiral scraper, the spiral scraper can remove the crude oil adhering to the inner wall of the pump barrel under the plunger, reduce the thickness of the adhered crude oil, so as to better form an oil film and reduce the crude oil adhering to the inner wall of the pump barrel The sand inside can reduce the accumulation of sand between the plunger and the pump barrel, reduce the wear of the plunger, and increase the service life of the oil well pump. At the same time, through the setting of the central shaft and the cross rod, as the plunger descends, the screw The scraper is rotated by the upward impact of the crude oil, and then drives the middle sealing ball to rotate, so that the crude oil forms a swirling flow and transmits upwards, reduces the resistance to the plunger, speeds up the transmission rate, and reduces the direct impact with the middle sealing ball, further accelerating the crude oil. transmission rate.

Description

technical field

[0001] The invention relates to the technical field of oilfield exploitation, in particular to an oil pump for oilfields. Background technique

[0002] The oil well pump is a kind of commonly used oil pumping equipment for pumping the crude oil in the well to the ground. Figure 8 As shown, the 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 5, and pump the crude oil from the bottom of the well to the top of the well and out of the output well. pressure, the upper sealing ball 7 and the middle sealing ball 6 are closed, and the lower sealing ball 4 is pulled up, so that the crude oil enters the pump barrel 2 from the oil inlet chamber 3, and at the same time, the crude oil on the upper part of the plunger 5 is lifted. When going down, the lower sealing ball 4 is closed, and the upper sealing ball 7 and the middle sealing ball 6 are opened. As the plunger 5 descends, the crude oil at the ...
