摘要
堵水调剖技术是油田提高水的波及率,改善水驱效果进而提高采油率的一项重要措施。简要综述了国内外油田堵水调剖剂的研究现状,总结了堵水调剖剂的设计思路、作用机理及应用现状,重点介绍了几种主要的堵水调剖体系,包括:聚丙烯酰胺基弱凝胶、体膨颗粒、含油污泥、微生物深部调剖、复合调剖、pH和温度响应型智能高分子水凝胶。对各种不同堵水调剖剂的优缺点进行了讨论和分析,并对新型堵水调剖剂的发展趋势进行了展望。
The technology of water shutoff and profile control is very important for enhancing sweep efficiency,improving the efficiency of water flooding and oil recovery.This review focuses on the research progress of water shutoff and profile control domestic and abroad.The design,mechanism and application of water shutoff and profile control agents are discussed in detail.Several systems are highlighted including:HPAM based weak gel,swellable particle,oily sludge,profile control by microbial,compound profile control system,stimuli-responsive hydrogel with pH-response and thermal-response mechanism.The strength and weakness of different water shutoff and profile control agents are discussed and compared.Finally,the prospect and future trend of new water shutoff and profile control agent is proposed.
