摘要
在化学驱过程中， 油水的界面扩张流变性对驱油机理和效果的影响极大。本文综述了化学驱体系中表面活性剂、 碱和聚合物对油水界面扩张黏弹性的影响规律， 重点剖析了不同类型物质在油水界面上的分布特征、 相互作用及界面膜结构， 分析了时间、 频率和浓度等因素与油水界面扩张黏弹性的关系， 为研究化学驱的渗流特征、 乳化机理、 油墙形成、 乳液后处理等问题提供参考和依据。参 64
Abstract
During chemical flooding process，oil-water dilational viscoelasticity had a great influence on oil displacement mechanism and effects. The influencing law of surfactant，alkali and polymer on the interfacial dilational viscoelasticity was summarized. The distribution characteristics， interactions and interface structures of different types of materials in oil-water interface were analyzed. The special attention was paid to the effects of time， frequency and concentration on oil-water interfacial dilational viscoelasticity. Methods， means， theories and viewpoints summarized in this review could provide reference and basis for studying the percolation characteristics， emulsification mechanism， oil wall formation and emulsion post-processing.
