无水低压气田后期开采不再难１９９６年４月８日，川西南矿区邓井关气田负压采气工艺试验喜获成功。３４号井日增产气２０００ｍ３。近两年该矿勘探生产效果不理想、天然气生产后劲不足，矿区在坚持对有水气田实施气举、机抽、泡排等采气工艺，大搞老井挖潜提高气田采收率... Waterless low-pressure gas field is no longer difficult to post-mining On April 8, 1996, Southwest Sichuan Dengjingng gas field negative pressure gas production test was a success. 34th well daily gas production 2000m3. In the past two years, the exploration and production results of the mine are not satisfactory, and the stamina of natural gas production is not enough. The mining area insists on implementing gas recovery processes such as gas lift, machine pumping and bubble discharge, etc.
