| 摘 要： | 长庆气田部分气井出现不同程度井筒积砂、混合脏物堵塞现象,对气井的正常生产和后期测试产生了一定的影响。针对这种情况,提出了连续油管胶液+氮气循环顶替+交替注入冲砂工艺。现场开展5口井试验,解堵作业成功率高,多储层伤害小,为关停气井复产措施提供了一种新途径。

| Abstract: | Some gas wells in Changqing gasfield are blocked by sand and mixed dirty materials in different degree,which has certain influence on normal production and late test of gas wells.In view of this situation,the continuous tubing rubber liquid+nitrogen circulation displacement+alternating injection sand-washing process is put forward.The field test of 5 wells shows that the success rate of plug removal is high and multi-reservoir damage is small,which provides a new way for shut-in gas wells to resume production. |
