泡沫调驱体系具有来源广、成本低、低伤害以及选择性封堵等优点，能有效改善地层非均质性、提高采收率。目前的泡沫调驱体系主要有常规液相泡沫、聚合物强化泡沫、冻胶强化泡沫和颗粒强化泡沫。总结了不同类型泡沫体系的特点、强化泡沫稳定性机理及泡沫在地层中的渗流规律，介绍了泡沫调驱体系的现场应用，指出泡沫调驱体系面临的问题以及研究方向。图13参90

Foam profile-controlling and flooding system has the advantages of wide source，low cost，low damage and selective plugging ability，which can effectively improve the heterogeneity and enhance oil recovery. The current foam profile-controlling and flooding system consisted of conventional liquid foam，polymer enhanced foam，gel enhanced foam and particle enhanced foam. The characteristics of different types of foam system，the mechanism of enhancing foam stability and the percolation law of foam in formation were summarized. The field application of foam profile-controlling and flooding system was introduced. The problems and research direction of foam profile-controlling and flooding system were pointed out.
