摘　　要：为抑制含水上升速度、保持较好的降水增油效果 ,用数值模拟技术对孤东八区聚合物驱后续注水注采方案进行了优化研究。结果表明 ,在注聚结束后的两年内 ,注采比保持 0 .8的效果最好 ,产液量调整的效果要好于注水量调整的效果。Optimization study on succeeding water injection (or injection?production) program after polymer flooding in Gudong 8 area is done using numerical simulation in order to restrain the raising velocity of water cut and keep good effect of decreasing water and increasing oil production. The result shows that best effect will be achieved at 0.8 injection?production rate, and the effect of adjusting fluid production is better than that of adjusting water injection rate within two years after the polymer injection finished. This study provides scientific basis for working out the field program for succeeding water injection after polymer flooding.
