摘　　要：本文介绍了大庆油田近期研制的八种单液法化学堵水剂及其应用技术，其中水玻璃和ＡＰ４高聚物两种堵水技术已通过局级鉴定，介绍较详。这些堵剂具有用量少、封堵半径小、强度高、成本低、工艺简便、必要时可解堵等特点。In this review articte two single-fluid watershutoff agents recently developed(water glass/crosslinker solution system and powdered polymer AP4 aqueous suspension),their properties and field test are introduced in some detail,six other single-fluid systems is under study(including cyanoacrylate,copolymer,terpolymer,hydrolyzed polyacrylonitrile/formaldehyde,compound GD and particulated epoxide) and is presented breafly.
