摘　　要：综述了目前应用较普遍的4种选择性堵水剂(聚合物类堵水剂、体膨型堵水剂、稠油类堵水剂、泡沫),总结出选择性堵水剂的4种作用机理,即吸附、捕集和物理堵塞机理、膨胀收缩机理、不稳定机理和油水通道分流机理。介绍了选择性堵水剂在现场应用中的影响因素(岩石润湿性、地层水矿化度)。为油田施工时堵水剂的选择以及方案的设计提供理论依据。The selective water shutoff agents had been applied widely in many oil fields. Four common selective water shutoff agents, such as polymer, swelling grain, viscous crude and foam were reviewed. And four kinds of mechanisms for water shutoff were summarized, such as adsorption-entrapment-physical plugging mechanism, swelling/shrinking mechanism, destabilization mechanism and oil-water segregated pathways mechanism. Meanwhile, the influencing factors of selective water shutoff agents for oilfield application were introduced, such as rock wettability and formation water salinity. This review would provide theoretical supports for the selection of agents and the design of projects in oilfield.
