Problems solved by technology

[0004] 2. Frequent hot washing of oil wells
[0008] (1) Workover is labor-intensive, takes up a long production time, and costs high
[0009] (2) The cost of well washing is high, the bottom of the oil well is easily damaged by the well washing fluid, and the recovery of production is slow
[0010] (3) Wax scraping, pipe scraping, etc. have high labor intensity, high operating cost, and there is a hidden danger of falling objects in the well
[0011] (4) Pickling has a corrosive effect on oil and carbon steel pipeline wells, affecting the effective economic life of oil wells
[0012] (5) There is a low-pressure area at the inlet of the oil well pump, which causes an unstable state of the liquid supply at the inlet of the oil well pump

Abstract

The invention discloses a manufacturing method of a paraffin-control anti-scale anticorrosion alloy suction aid. The method includes: making steel J55 or N80 into the suction aid, making nitrates or sulfates or chlorides of silver, copper, zinc, tin, nickel, iron, manganese and rare-earth into an electroplating liquid I, preparing an electroplating liquid II by using sodium potassium tartrate as a complex, adjusting pH of the electroplating liquid II to 12-13.5 by using sodium hydroxide to obtain an electroplating liquid III, electroplating the suction aid in the electroplating liquid III by using metallic titanium or graphite as a positive electrode and the suction aid as a negative electrode, and performing thermal treatment at 300-600 DEG C to obtain the finished paraffin-control anti-scale anticorrosion alloy suction aid. The aid is capable of degrading paraffin, colloid and asphaltene in crude oil, preventing the precipitation and condensation of sulfates or carbonates of calcium, magnesium, barium and strontium, and preventing paraffin jamming and scale jamming on the wall of a suction pump, a sucker rod or a suction pipe.

Description

technical field [0001] The invention belongs to the technical field of oil exploitation technology, and in particular relates to a method for manufacturing an anti-wax, anti-scaling and anti-corrosion alloy pumping aid device. Background technique [0002] In the process of oilfield oil recovery and development, the water-bearing crude oil in the wellbore has undergone great changes in temperature and pressure compared with the three phases of oil, gas and water in the formation, which makes the paraffin, colloid, asphaltene, calcium, magnesium, barium and strontium in the oil and water components Sulphate and carbonate are easily precipitated and condensed on the wall of the oil pump, sucker rod, and oil pipe, causing wax sticking and scale sticking, making it impossible to carry out normal production. In addition, supply liquid in the later stage of development of low-pressure and low-permeability reservoirs Insufficiency is a common phenomenon. To solve this problem, the...
