An oil well pump with anti-sand and anti-scaling

Abstract

The invention discloses a sand and scale-proof oil well pump, belonging to the technical field of oil pumps, comprising 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 inside the pump body shell , the first end of the oil delivery pipe is fixedly connected with the scraper in the oil pumping device, the second end of the oil delivery pipe is slidably arranged inside the oil storage device, the driving device is installed between the oil storage device and the casing of the pump body, and the driving device drives the oil delivery pipe to slide, Further, the oil delivery pipe controls the action of the oil pumping device, changes the internal space of the oil pumping device, and realizes oil pumping. The softener is installed inside the shell of the pump body, and the softener communicates with the oil pumping device for injecting the softening agent into the inside of the oil pumping device; The oil pumping process directly realizes the removal of grease and the automatic collection and discharge of mud and sand, which effectively prevents mud and sand from clogging the device, and has a high degree of automation.

Description

Technical field [0001] The present invention relates to the field of oil pump, and Background technique [0002] The oil fuel pump refers to a downhole device that drives the inner crude oil to the ground by the suction machine. The ordinary pumping pump consists mainly of the pump cartridge, inhaled valve, piston, and exclude the valve. According to the fixed manner of the pumping pump, it can be divided into a tubular pump and a rod pump, and the conventional oil fuel pump is often in the process of use. In the case of mud clogging and sediment deposition, it has been inconvenient to use, and the application number will be disclosed in the application number. Working cylinder and outer working cartridge; there is a first passage between the inner working cartridge and the outer working cartridge; the bottom end of the drain is mounted into oil valve and drainage roller; the top of the oil can be connected to the second channel. The top of the oil can communicate with a third ch...

AI Technical Summary

Problems solved by technology

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
