摘要

油包水乳状液具有良好的流度控制能力，可以扩大波及体积，提高驱油效率。基于油水体系的乳化机理，综述了原油组成、水相组成和乳化条件等对油包水乳状液稳定性影响的研究进展，论述了油包水乳状液在提高采收率方面的应用。

Abstract

Water-in-oil emulsion has good mobility control ability，which can expand swept volume and improve oil displacement efficiency. Based on the emulsification mechanism of oil-water system，the effects of crude oil composition，water phase composition and emulsification conditions on the stability of water-in-oil emulsion were reviewed，and the application of water-in-oil emulsion in improving oil recovery was discussed.
