低渗透油气藏在世界范围内分布范围广,储量大,在新探明储量中占得比例越来越大,是全球油气资源增产的主要来源,合理高效的开发低渗透油藏中的油气资源,是未来面临的主要问题.泡沫驱油作为继水驱、气驱之后新的驱油方式,结合了气体和泡沫的优点,以独特的优势越来越得到人们的重视,是低渗透油藏提高采收率的又一个重要途径.分析了泡沫驱相对于其他驱油方式的优势,概述了泡沫驱油的驱油机理,简要分析了空气泡沫驱、氮气泡沫驱各自特点,对泡沫驱油在国内外油田的应用现状做了介绍.对泡沫驱油存在的问题做了阐述,并提出了泡沫驱油的发展方向.%TheLow permeability oil and gas reservoirs has a wide range of distribution in the world, and large reserves, it accounts for more and more proportion in the new reserves, it is the main source of global oil and gas resources, reasonable and efficient development of low permeability reservoir is the main problem in the future. Foam flooding, as a new way of the displacement after water flooding and gas driving, combines with the advantages of the gas and foam, getting more and more people's attention because of its unique advantages, it is an important way to enhance oil recovery in low permeability reservoirs. In this paper, compared with other oil displacement methods,the advantages of foam flooding were analyzed, and the mechanism of oil flooding was summarized. The characteristics of air bubble flooding and nitrogen bubble flooding were briefly analyzed, application of foam flooding in oil fields at home and abroad was introduced. Some problems in the foam flooding were described, and the development direction of foam flooding was discussed.
