摘　　要：某块自1991年投入开发,至今已25年,目前区块油井进入高轮次、高采出程度、高含水阶段,地层压力低、油井吞吐效果差等问题严重影响了区块的产量,近几年,通过精细地层对比,逐单层分析比对,寻找采出程度低的油层重新利用,实施后油井平均日产油明显提高,取得了较好的效果。X block has been developed since 1991 and now it has been 25years.Currently,it has entered into multi-cycle,high degree of reserve recovery,high water cut stage,low stratigraphic pressure and the effect of steam stimulation is getting worse.All these problems have seriously affected the block production. In recent years,through fine stratigraphic correlation and monolayeranalysis and comparison,low recovery degree of reservoir is found out and reused again. After the implementation,average daily oilproduction volume is significantly improved and good results are acquired.
