Sand and scale prevention oil well pump

Abstract

The invention discloses a sand and scale prevention oil well pump, and belongs to the technical field of oil pumps. The oil well pump comprises an oil storage device, a driving device, a softener injection device, a pump body shell, an oil delivery pipe and an oil pumping device, the oil pumping device is arranged in the pump body shell, and the first end of the oil delivery pipe is fixedly connected with a scraper blade in the oil pumping device; and the second end of the oil delivery pipe is arranged in the oil storage device in a sliding manner, the driving device is installed between the oil storage device and the pump body shell, the driving device drives the oil delivery pipe to slide, then the oil delivery pipe controls the oil pumping device to act, changes the internal space of the oil pumping device and achieves oil pumping, a softener is mounted in the pump body shell, and communicates with the oil pumping device, and the softener injection device is used for injecting the softener into the oil pumping device; and oil dirt removal and automatic collection and discharge of mud and sand are directly achieved in the oil pumping process, the mud and sand are effectively prevented from blocking the device, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of oil pumps, in particular to an anti-sand and anti-scaling oil well pump. Background technique [0002] The oil well pump refers to the downhole device driven by the pumping unit to lift the crude oil in the well to the ground. Ordinary oil well pumps are mainly composed of four parts: pump barrel, suction valve, piston, and discharge valve. According to the fixing method of oil well pumps in the well, they can be divided into tube pumps and rod pumps. Conventional oil well pumps are often used during use. The occurrence of mud and sand blockage and grease deposits brings inconvenience to the use. The patent application number CN202110654587.8 discloses a solid plunger multi-proof and high-efficiency oil well pump, including a drainer. There is a first passage between the inner working cylinder and the outer working cylinder; the oil inlet valve and the oil discharge valve are installed at the bottom of t...

Ordinary oil well pumps are mainly composed of four parts: pump barrel, suction valve, piston, and discharge valve. According to the fixing method of oil well pumps in the well, they can be divided into tube pumps and rod pumps. Conventional oil well pumps are often used during use. The occurrence of mud and sand blockage and grease deposits brings inconvenience to the use. The patent application number CN202110654587.8 discloses a solid plunger multi-proof and high-efficiency oil well pump, including a drainer. There is a first passage between the inner working cylinder and the outer working cylinder; the oil inlet valve and the oil discharge valve are installed at the bottom of the drainer; the top of the oil inlet valve is connected with the second passage, and the drain The top of the oil valve is connected with a third channel; the bottom of the drainer is provided with a fourth channel communicated with the second channel, and a fifth channel communicated with the third channel; the bottom of the oil inlet valve is provided with a horizontal inlet The oil hole and the sixth channel vertically arranged; the bottom end of the second channel is connected with the sand settling channel; the sixth channel is connected with the oil inlet valve; the bottom of the sand settling channel is connected with the sand settling pipe

This prior art solves the problem of mud and sand clogging to a certain extent by setting the sand settling pipe, but the function is single, the device cannot automatically clean the collected mud and sand, it is inconvenient to use, and it cannot deal with the technical problem of oily dirt. Therefore, the present invention provides a A kind of anti-sand and anti-scaling oil well pump realizes the cleaning of mud, sand and oil dirt while pumping oil, and has the characteristics of high degree of automation and various functions
