| 摘 要： | 利用毛细管加注泡沫排水采气技术是最近几年发展起来的一种新的作业技术,主要应用于因井底积液导致产量下降或停产的采气井,通过作业消除积液影响恢复产量。针对蜀南气矿低压低产量气井携液能力差、井底易积液等生产现状,气矿引进了撬装式毛细管加注泡沫排水采气设备,对坝17井等井站进行排水采气现场试验。产气量从试验前的0.3×104m3/d增加到试验后的1.1×104m3/d,增幅为266.7%;产水量也由25.3 m3/d增加到41.5 m3/d,增幅64.03%,增产效果明显。试验结果表明毛细管加注泡沫排水采气技术是一种高效、实用的排水采气技术。

| Abstract: | In recent years,a new technology of dewatering gas lift using capillary to inject bubbles into wells has been developed,which is mainly applied to production decline or dead gas wells caused by liquid loading in order to eliminate the impact of liquid loading and resume the production.Because of the current production situation of Shunan Gasfield which is of low pressure,low production and poor liquid lifting ability,new technology of dewatering gas lift was introduced.The result of field test in Ba17 gas w... |
