摘　　要：介绍了化学转向暂堵技术分别应用于酸化、压裂及酸压施工中的工作原理以及它们之间的联系与区别。综述了暂堵剂的研究历史以及目前使用较为普遍的几类暂堵剂,包括纤维暂堵剂、颗粒暂堵剂、聚合物交联暂堵剂、吸水膨胀型暂堵剂、泡沫暂堵剂等。总结了各类暂堵剂在施工时封堵高渗透层的作用机理及存在的优缺点,并对暂堵剂的发展及应用进行了展望。The operational principles of chemical temporary plugging techniques applied in acidizing,hydraulic fracturing and acid fracturing construction as well as the distinction and linkage between them were introduced.Several types of currently used temporary plugging agents and their research histories were reviewed,including fiber temporary plugging agent,granular temporary plugging agent,cross-linked polymer temporary plugging agent,water-absorbent expansive temporary plugging agent and foam temporary plugging agent.In addition,plugging mechanism along with the merits and drawbacks of various temporary plugging agents were summarized.Accordingly,the developments of them in recent years were prospected.
