泡沫助采在油田中的现状与发展前景

Present Situation and Development Prospect of Foam Flooding in Oilfield

泡沫作为一种良好的驱油剂已逐渐为人们所认识,它能够极大提高注入流体的表观黏度,增加波及面积,提高采收率,是一种很有发展前途的提高采收率的新方法。本文综述了国内外泡沫驱技术的应用与研究进展,并进一步分析了泡沫驱的驱油机理、影响泡沫稳定的因素以及存在的问题。

As a good kind of flooding method, foam flooding was gradually known by people, because of its character of greatly improving the apparent viscosity of injected liquid, expanding swept area and enhanced oil recovery （EOR）, it had been developed to be a future new EOR method. In this paper, foam flooding technology in the application and research developments were summarized in China and abroad. The foam enhanced oil recovery mechanism, factors affected foam stability, problems of existence and so on, were also analyzed.
