摘　　要：介绍了泡沫钻井液析液理论和实验方法的研究进展情况,分析了具有分析和数值解的标准及扩展析液理论,讨论了影响泡沫稳定性和消泡的微脱水因素。其中重点分析了气液界面的物理化学性质对泡沫析液的影响以及通道和节点控制析液区域的相关泡沫结构性质。重要的研究结果有:泡沫压力降技术可以在具有可变(或恒定)的Plateau边界条件下研究泡沫的析液行为;在研究通道和节点控制等2类重要析液区域时,自由和受迫析液方法也是非常实用的技术。This paper has investigated on the recent works on the drainage mechanisms of foam drilling fluids,including both the advanced theoretical and experimental studies into foam drainage,standard and extended drainage theories with analytical and numerical solutions.Highlights of recent works include the effect of physicochemical properties of the gas-liquid interface on foam drainage,and the foam-structure related properties governing the channel-and node-dominated drainage regimes.Important results obtained using the foam pressure drop technique which allows a systematic investigation of foam drainage with the constant and varying Plateau border radius are discussed.The free and forced drainage methods have also been the useful experimental techniques for revealing the two important drainage regimes by the channels and the node.
