三元复合驱技术迅速发展,在矿场试验中取得了较好的增油降水效果,但是采出液中残余的聚合物、碱、表活剂使采出液乳化严重,导致油水分离困难。本文进行三种破乳剂对两口三元井采出液室内破乳评价室验,通过破乳效果分析,筛选出一种适合三元复合驱采出液的破乳剂,并进行了现场实验,取得了较好效果。 The rapid development of ASP flooding technology has yielded better oil precipitation effect in the field tests. However, the remaining polymer, alkali and surfactant in the produced fluid emulsified the produced fluid, resulting in difficulties in oil-water separation. In this paper, three kinds of emulsion demulsifiers were used to evaluate the room demulsification chamber of the two three-well wells. Through demulsification analysis, a kind of demulsifier suitable for the ASP flooding fluid was screened and tested in-situ A better effect.
