针对曙光油田在蒸汽吞吐开采过程中存在的原油粘度高,乳化严重,回采水率低等问题,研制一种集新型、调剖、降粘、洗油、助排、破乳、解堵、润湿等诸多功能于一身的驱油剂,实现一剂多效、复合高效,并在吞吐基础上,随蒸汽注入油层,达到降低原油粘度,改善原油的流动性,降低界面张力,提高油井产量的目的。通过在曙光油田不同类型井的现场试验,取得了比较好的效果。
In view of the problems of high viscosity crude oil, severe emulsification and low recovery water rate in the process of steam huff and puff, Shuguang Oilfield has developed a new type of gas control system with the features of new type, profile control, viscosity reduction, oil washing, drainage, demulsification, Wet and many other functions in a drive agent, to achieve a multi-effect, complex and efficient, and on the basis of throughput, with the steam injected into the reservoir, to reduce the viscosity of crude oil to improve the mobility of crude oil, reduce interfacial tension and improve oil production purpose. Through the field test of different types of wells in Shuguang Oilfield, good results have been achieved.
