摘要
乳化作用是化学驱提高采收率的重要机理之一,在复合驱过程中乳化作用能明显提高采收率。本文介绍了化学驱中表面活性剂形成胶束的结构、性质和增溶作用,概述了微乳液结构和性质及其在采油方面的应用,介绍了乳状液的稳定性及其在提高采收率方面的作用,归纳了复合驱乳化研究发展的方向。
For chemical flooding,emulsification was one of the important mechanisms of enhanced oil recovery(EOR). In the process of compound flooding,the emulsification could improve oil recovery significantly. The structure,properties and solubilization of surfactant-forming micelles in chemical flooding were introduced in this paper. The structure and properties of microemulsions and their applications in EOR were summarized. And the stability of emulsions and their effects in EOR were introduced. Finally,the development direction of compound flooding emulsification was summarized.
