运用简化的黑油模型,对砂岩油藏层内堵水机理进行了数值模拟研究,得出了一些定性的认识和定量的结论。根据得出的结论,对高含水的L36断块整体堵水进行模拟,预测了堵水效果,从8套方案中优选出调整治理方案。该方案实施后,区块综合含水上升率由每年的2%下降为零,产量递减速度得到明显控制,累计增油量9066 t,而预测增油量为11020 t,吻合率达82%,为同类油藏的综合治理提供了一种有效的方法。

After the mechanism of water shutoff has been studied by numerical simulation with black oil model, some qualitative and quantitative realizations and conclusions are given in this paper. Based on the realizations and conclusions, the entirety water shutoff of fault-block L36 is simulated and studied. As a result, the effect of water shutoff on the reservoir of fault-block L36 is forecasted and the better scheme of adjustment is selected from eight projects. By the end of the using, the water cut of this fault was fallen from 2% to zero, the increasing production of oil is 9066 t. In conclusion, this effective method could be used in any reservoir with same conditions.
