摘　　要：以我国油气田压裂所用的暂堵球、暂堵剂等2大类产品为主线,系统总结了不同工艺及配方合成的暂堵产品的暂堵机理、性能特点及应用现状,阐述了各产品的溶解特性,结合油气田绿色环保开发需求提出了现有水溶性暂堵球、暂堵剂存在的问题,并对暂堵产品未来的发展方向进行了展望。Based on the temporary plugging balls and temporary plugging agents used in fracturing of oil and gas fields in China,this paper systematically summarized the temporary plugging mechanism,performance characteristics,and appli-cation status of temporary plugging products synthesized through different processes and formulas.The dissolution char-acteristics of each product were introduced,and the existing problems in the water-soluble temporary plugging balls and temporary plugging agents were pointed out through a combination with the requirements for the development of green environmental protection of oil and gas fields.Finally,the future development direction of temporary plugging products was prospected.
