摘　　要：大庆油田萨北开发区综合含水率目前已跃居全油田第二高,如何找准剩余油分布位置并制定合适的挖潜对策已成为现阶段降本提效的关键。与以往单纯从开发角度分析不同,依靠近年来井震结合油藏描述技术精度的逐步提高及成果的广泛应用,现已形成配套的动静结合潜力预测方法,并针对不同类型剩余油提出了相应的挖潜对策。主要包括断层再认识措施潜力分析,断层边部聪明井高效挖潜模式以及储层预测潜力综合调整3个方面。研究成果有效指导了特高含水期措施挖潜并已见到了实效。In Sabei Development Zone of Daqing Oilfield,its comprehensive water cut has now ranked the second in the whole oilfield,how to get the remaining oil distribution location and develop appropriate countermeasures for tapping the potential has become the key to reduce the cost and improve its development effect.Different from previous prospects from the aspects of unique analysis of oilfield development,based on the gradual improvement and wide application of research result of accurate reservoir description in combination of logging with seismic data,a set of methods were established for tapping the potential of remaining oil in combination of dynamic and static data.Corresponding countermeasures were proposed for tapping the potential of different types of remaining oils.The countermeasures include faulted zone reidentified for analyzing the potential tapping measures,the pattern for high efficient potential tapping for smart well on the edge of faults and comprehensive adjustment of potential tapping for reservoir prediction.It provides a guidance for potential tapping at the extra-high water-cut stage and good effect is obtained.
