三元复合驱采出液破乳技术研究

Study on Demulsifying Technology for Produced Liquid in 3-Dimension Complex Drive

采用光学显微镜和电子显微镜研究了聚丙烯酰胺、表面活性剂和碳酸钠的三元复合驱油体系与克拉玛依油田二中区原油形成的乳状液界面膜性质、粒度尺寸和微细结构。考察了三元驱油组份对乳状液破乳脱水的影响规律，并对脱水过程油水中间层的成因及消除中间层的方法进行了探讨。针对模拟采出液的性质对合成的不同类型的破乳剂进行了评选，从中筛选出适用于二中区模拟三元复合驱采出液的破乳剂，提出了对路破乳剂的研制方向。

In accordance with the properties of produced liquid, the author chooses the different types synthetic demulsifying agents and in Which the onethat suits for simulate 3-udimension complex driveproduced liquid in Erzhong district was chosen,theauthor also put forward the deve1oping direction ofdemulsifying agent.
