Antiscaling alloy oil sucking pump

Abstract

The invention discloses an alloy anti-fouling oil extractor including the short pump canister and long plunger piston. The up connecting hoop is connected to the short pump canister top; which is fixed with the up scraping device; the lower is connected with the down connecting hoop which the lower is connected with the up lengthen pipe which the lower is connected with the up lengthen pipe connecting hoop which is fixed with the down scraping device. The up lengthen pipe connecting hoop lower is connected with the down lengthen pipe which the lower is connected with the lower lengthen pipe hoop which the lower is connected with the fixed valve cover which the lower is connected with the fixed valve seat joint; the alloy welding layer is sprayed on the inner side of the short pump canister, the up lengthen pipe and the down lengthen pipe. The invention can resist the abrasion, the rotten and dirty. The up and down scraping devices and the scraping ring, the valve ball, the valve seat are made by the hard alloy material. The invention can avoid block the pump to improve the using life.

Description

technical field [0001] The invention relates to the technical field of oil well extraction devices in petroleum exploitation, and belongs to an anti-scaling oil pump, in particular to an anti-scaling oil pump with a long plunger, a short alloy pump barrel and an adjustable position-adjustable upper and lower scraping device. Background technique [0002] At present, most oilfields in my country have entered the middle and late stage of development, and the geological conditions are becoming more and more complex. Reinjection changes the properties of the produced fluid, leading to corrosion and scaling in the production well, which has a great impact on crude oil production. In the process of oil recovery, it is manifested in the following aspects: [0003] 1. Scaling caused by corrosion makes the gap between the pump barrel and the plunger gradually smaller, forming a stuck pump; [0004] 2. Scaling of the valve ball and valve seat causes poor sealing and serious leakage, ...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the difficulties caused by the corrosion and scaling of the oil pump in the oil production well to the production of crude oil and overcome the deficiencies in the prior art, the purpose of the present invention is to provide an alloy anti-scale oil well pump with simple structure, convenient use and long-lasting effect. Remarkable performance can greatly extend the service life of the oil well pump; it can remove and block the sand accumulation and scale on the friction surface between the plunger and the pump barrel during work, and can effectively prevent the occurrence of pump jam accidents during work
