摘要 在井下作业和酸化过程中,大量液体进入了井筒和地层中,导致气井井口压力低而不能正常开井生产;如不彻底将这些液体排出井外,不但影响气井产量,甚至会产生二次污染,大大降低酸化措施效果。针对上述问题,又综合考虑到液氮气举费用较高,借鉴液氮气举的工作原理,2008年在芳深X井进行二氧化碳气举排液现场试验,取得了较好的排液效果,气井均恢复了正常生产,理论分析与现场试验表明:液态二氧化碳气举气井是可行的。 Down hole operation and acidization process bring a lot of liquid into well bore and formation which result in the low well head pressure and unable to produce normally. If don't dispel the liquid out of the well,the well production will he affected and secondary pollution will be generated.It will reduce the low acidization measurements effect. Based on the above problems, and combined with the high cost of liquid nitrogen gas lift and the working principles of liquid nitrogen gas lift, the Carbon dioxide experience in 2008 proved that liquid Carbon dioxide for gas lift at well is feasible.
