摘　　要：油田进入高含水开发阶段,封堵井层越来越多,封堵时间也越来越长,造成封堵层的水压力梯度发生了变化,剩余油进行了重新分布。通过运用灰色理论预测高含水井层系的含水变化情况,并进行去堵求产,取得了较好的效果。More and more intervals in producers are plugged and the time is also becomes longer as oilfields enter into high water cut stage of development, resulting in change of water pressure gradient and redistribution of the remaining oil in the plugged layers. Grey theory is used to predict variation of water content in the plugged intervals in wells with high water cut, and calculate production through unplugging.

关 键 词：剩余油 可采储量 灰色模型 效果
