摘　　要：介绍了大庆油田高含水后期细分注水技术与实践，对“两小一防”（小夹层、小卡距，防止在测压时封隔器上部高压向低压层窜动）细分注水技术和液力投捞细分注水技术从管柱的结构、井下工具原理、性能、参数以及配套技术的应用等方面进行了比较系统的阐述。实践证明，该项技术的研究与应用，提高了可采储量的动用程度，产生了巨大的经济和社会效益。This paper introduces the research and application of subdivision water injection technology at late high water cut stage in Daqing Oilfield. This paper systematically describes the 'one small and one prevention (small intercalation, small stuck distance and prevention the interporosity flow when pressure measurement)' and hydraulic balllng subdivision water injection technologies in terms of string structure, downhole tools working principles, properties, parameters and the application of matching techniques. Field test proved that the technologies had increased the producing degree of recoverable reserves, and had resulted in great economic and social benefits.
