Several Times Adjustment Well Result Analysis and Evaluation in the High Water-bearing Oilfield

摘要: 作者对高含水期油田多轮次调剖井按照剂量大小、先后次序进行了调剖效果分析后得出结论:多轮次调剖堵水的效果是依次递减的, 但可通过优化多轮次调剖系列堵剂、适当增加堵剂用量、优化每一轮调剖的封堵时机和注入压力, 减缓多轮次调剖效果的逐次递减。

Abstract: According to the amount of water shutoff agent, the authors undergo several times adjustment well result analysis successively. The conclusion is the water shutoff effect is decreased, but we can better the water shutoff agent, increase its dosage, and optimize the shutoff time and injection pressure to solve the problem.
