摘　　要：安塞油田延安组A油藏是典型的构造-岩性油藏,具有一定的底水和边水天然能量驱动特征,进入中高含水开发期后,稳油控水难度加大。为维持年产油量合理增长的要求,结合油田矿场实际生产数据,建立以油田产能递减规律-甲型水驱特征曲线-翁文波的Logistic旋回模型相结合的确定合理注采比的一套方法,并根据历史开发动态进行调整。通过2016年数据拟合结果和实际生产数据对比,该方法对于确定延安组油藏中高含水期油田的合理注采比有一定的指导意义和实用价值。A reservoir in Yan＇an formation of Ansai oilfield is a typical structural-lithologic reservoir with certain bottom water and edge water natural energy driving characteristics. After entering middle and high water cut development period, it is difficult to control water and increase oil. In order to maintain a reasonable growth of annual oil production, a method for determining reasonable injec- tion production ratio is put forward by combining oilfield productivity decline law, A-type water flooding characteristic curve and Lo- gistic cycle model of Weng Wenbo phase, and it is adjusted according to the historical development trend. The comparison of the fitting result using the actual production data in 2016 with the actual production data method shows that the method is of certain guiding significance and practical value for determining the reasonable injection production ratio of the oil reservoirs in Yanan formation in high water cut stage.
