Manufacturing method of paraffin-control anti-scale anticorrosion alloy suction aid
2015
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.
