表面活性剂驱的驱油机理与应用

Flooding Mechanism and Application of Surfactant Flooding

通过对表面活性剂分子在油水界面的作用特征、水驱后残余油的受力情况以及表面活性剂对残余油受力状况影响的分析,对表面活性剂的驱油机理进行了评述。根据对国内驱油用表面活性剂研究现状的分析,结合目前开展的研究工作,认为开发研制廉价、高效表面活性剂是开展表面活性剂驱油及其相关驱油技术的关键,并对表面活性剂及其相关驱油技术的应用前景进行了展望。

On a analysis basis of the interaction characteristic of surfactant molecules at the interface of water and oil, force condition of residual oil after water flooding and the effects of surfactant on the force condition of residual oil, the mechanism of surfactant flooding was reviewed. According to the present research situation of oil - displacement surfactant at home and some research work in our laboratory, it was taken for granted that the research and development of oil - displacement surfactant with low cost, high performance was a key to the development and application of surfactant flooding and related flooding technology. The application prospects of surfactant flooding and related flooding technology were forecasted.
