摘要
针对普通稠油油藏水驱采收率低,而且经济上不适合于热采的特点,介绍了国内外化学驱提高普通稠油采收率技术的一些研究进展,主要包括聚合物驱,碱驱,碱/表面活性剂驱。综述了各种方法提高普通稠油采收率的研究现状和机理研究进展,并指出了不同方法存在的问题和当前的研究热点。
On account of the low oil recovery by water flooding for heavy oil reservoirs and uneconomic for the application of thermal recovery methods,recent developments of enhanced heavy oil recovery by chemical methods was presented,including polymer flooding,alkaline flooding and alkaline/surfactant flooding,and the recent studies of the flooding mechanisms for enhanced heavy oil recovery were summarized,and the problems occurred in various methods and the current study hot spots were pointed out.
