摘要
以聚乙烯醋酸乙烯酯、极性基团物质改性合成的聚丙烯酸酯SDG - 6双功能处理剂 ,对凝点 40℃左右、黏度 10 0 0 0mPa·s以下的原油降凝率达 70 % ,降黏率达 95 %以上。同时降黏降凝效果好 ,经两口油井试用 。
The modified polyacrylate dual function agent(named SDG-6) was synthesized from poly(ethylene-vinyl acetate) and polar groups.On treating crude oil with pour point about 40 ℃ and viscosity below 10 4 mPa·s,the rate of pour point lowering attained 70% and the rate of viscosity lowering was above 95%.It is effective on lowering pour point and viscosity at the same time.This initially solves the problem of exploiting and transporting high pour point thick crude oil through trying out in two oil wells.
