摘要

针对常规注蒸汽采油中蒸汽超覆和指进、且洗油效率低的特点，介绍了国内外表面活性剂体系改善注蒸汽采油开发效果的一些研究进展，主要包括蒸汽／泡沫剂、蒸汽／降黏剂和蒸汽／增油助排剂。综述了各种方法的研究现状、作用机理及适用条件，并指出了不同方法存在的问题和发展的方向。参42

Abstract

On account of the steam overlap or fingering and low displacement efficiency in the conventional steam stimulation,recent developments of surfactant system assisted steam stimulation in heavy oil were presented,including steam/foam agent,steam/viscosity reducer and steam/cleanup agent.The recent studies,mechanism and application conditions for the three methods were summarized.Problems existed in various methods and their developing directions were pointed out.
