介绍了泡沫流体在近井地带中的应用，包括泡沫酸处理、压裂、混排解堵、携砾石充填及压水锥；总结了泡沫流体在地层中的应用现状，包括泡沫堵水堵气和泡沫调驱。从理论研究及施工工艺两个层面指出了目前泡沫流体增产系列技术的前景及发展方向。

The application of foam fluid in the immediate vicinity of wellbore was introduced, including foam acidizing, fracturing, plug removing, gravel packing and water-coning controlling. The application status of foam fluid in the formation was summarized, including foam for water and gas plugging and profile control and flooding. The prospect and development direction of foam fluid stimulation techniques from the aspects of theoretical study and construction technology were proposed.
