表面活性剂驱油藏适应性研究

Researches of Reservoir Adaptability by Surfactant Flooding Process

在广泛调研国内外文献的基础上,重点论述了砂岩油藏构造特征、沉积环境、储集层特征、流体性质及开采方式等因素对表面活性剂驱油的影响,对砂岩油藏表面活性剂驱替的适应性进行了分析与总结。结合美国在20世纪80—90年代采用表面活性剂体系开采的油田实例,对碳酸盐岩油藏采用表面活性剂驱替进行了积极的探索。通过评价表面活性剂驱对油藏的适应性,为优选提高油田原油采收率方法提供新的思路。

This paper focuses on various impacting factors on surfactant flooding,such as reservoir structure,sedimentary environment,reservoir fluid property,rock type and development process in sandstone reservoirs and analyzes and summarizes the adaptability of sandstone reservoir developed by surfactant flooding process.Integrated with case studies from American oilfields development by surfactant flooding process in 1980s^1990s,approach to carbonate reservoirs development by surfactant flooding process is conducted,which provides a new idea for EOR.
