摘　　要：开发进入中后期的中高含水油藏,由于各种化学驱油方式存在着一些因素的制约,使得泡沫驱油这种实施成本相对较低,施工工艺相对简单,提高采收率比较明显的驱油方式成为一种主要的三次采油方式。泡沫驱油方式的不断发展,到目前为止已经发展有氮气泡沫驱油、空气泡沫驱油、CO_2泡沫驱油等多种方式。本文主要从宏观和微观方面介绍泡沫在多孔介质中的渗流以及改善吸水剖面、增加驱油效率、提高采收率等方面的机理和规律。In the middle and late stage of development into the middle and high water-bearing reservoirs,due to the constraints of various chemical flooding methods,the implementation cost of foam flooding is relatively low and the construction technology is relatively simple,and the oil displacement method with obvious enhanced oil recovery ratio has become one of the main tertiary oil recovery methods.With the development of foam flooding methods,nitrogen foam flooding,air foam flooding and CO2foam flooding have been developed up to now.This paper mainly introduces the mechanism and law of foam seepage in porous media,improving water absorption profile,increasing oil displacement efficiency and increasing oil recovery ratio from macro and micro aspects.
