摘　　要：针对杜229断块南部兴V组出水问题,精细统层对比,深化油藏地质研究;结合油井生产动态,开展全过程水性跟踪和示踪剂监测试验.其结果不仅确定了边水水侵部位、层位及方向,而且对水侵速度、能量大小及涉及程度有了全新的认识.在此基础上制定并实施了科学有序的堵水、堵排结合治水、综合治水方案,在已实施的26井次堵水措施中,成功率100%,累计增油6.1×104t,确保了全块持续高产、稳产.其工作思路和方法,不仅对开发同类型油藏有现实意义,而且对基础油藏的开发也有借鉴意义.In accordance with the problem of water producing in Xing-V formation in the south of block Du229, fine correlation of formations is conducted, and reservoir geology is studied deeply. Combining with production performance, full-course tracing of water property and tracer monitoring are carried out. Not only are the location, horizon and direction of edge water invasion adequately settled, but also a new understanding is obtained about water invasion velocity, energy and extent. On this basis, a comprehensive plan of water blocking, draining, or both of them following scientific procedures is made and implemented. After applying to water plugging for 26 well times, its success ratio is 100 % , cumulative oil increment is 6. 1 ×104t, thus ensuring continuing stable high production in the whole block. This thought and method have practical significance for developing similar reservoirs, and are reference to basic reservoir development.
