摘　　要：重点分析了CO_(2)响应型封窜剂的分子组成、响应机理和封窜性能,综述了近年来国内外用于辅助CO_(2)驱智能封窜剂的研究进展。用于CO_(2)流动控制的常规封窜剂存在难注入与封堵效率低等不利因素,基于非共价作用的封窜剂可以对CO_(2)做出智能响应,由于其封堵能力强、注入性好,在辅助CO_(2)驱中控制气窜和提高原油采收率中效果显著。介绍了具有应用潜力的新型CO_(2)响应体系,并讨论了其未来发展趋势与应用前景。CO_(2)Flooding has been widely used in the petroleum industry for decades, especially in light-medium reservoirs near late maturity.The injected fluid is prone to fingering and severe gas channeling in the fracture network in many CO_(2)-EOR reservoirs because of low permeability and high heterogeneity.The intelligent plugging agent based on non-covalent interaction has strong plugging ability and good injectivity, and is effective in controlling gas channeling and improving oil recovery in auxiliary CO_(2)flooding.The research progress of intelligent channeling plugging agent used to assist CO_(2)flooding is reviewed, and the molecular composition, mechanism and performance of CO_(2)responsive channeling plugging agent are analyzed, and its future development trend and application prospect are discussed.
