目前出现的由于有机质的沉积使得原油在管线运输过程中出现输送阻力大,耗电量高,安全性难以保障等问题,使用DRIVE原油萃取剂进行室内和现场评价实验,包括稠油油垢溶解性、模拟管道降压减阻实验进行评价,发现DRIVE原油萃取剂具有良好的原油清洗力,降粘防蜡效果明显,可以明显降低原油输送阻力,改变原油润湿性,提高原油流变性,改善原油品质,从而减小原油在集输过程中的流动阻力,改善其流动性,降低原油的集输成本。
At present, DRIVE crude oil extractant is used for indoor and on-site evaluation experiments due to the deposition of organic matter which causes the problems of large transportation resistance, high power consumption and difficult safety protection of crude oil during pipeline transportation. The experiments include heavy oil grease solubility, The experimental results show that DRIVE crude oil extractant has good ability of cleaning crude oil, reducing viscosity and preventing wax obviously, can significantly reduce the resistance of crude oil transportation, change the crude oil wettability, improve the rheology of crude oil and improve the quality of crude oil , Thus reducing the flow resistance of crude oil during the collection and transportation, improving its liquidity and reducing the collection and transportation costs of crude oil.
