6月5日,中国石油大庆油田公司采气分公司成功完成首批3口深层气井的泡沫排水试验,日增产天然气3.5万立方米以上,为大庆低产气井增产稳产提供了技术支撑。大庆采气分公司地质工艺研究所负责人表示,泡沫排水技术就是在井筒存在积液的气井内注入泡排剂,借助天然气流动的搅拌作用,使之与井底积液充分混合,产生大量比较稳定的含水泡沫体 On June 5, the oil and gas branch of PetroChina Daqing Oilfield Company successfully completed the first batch of 3 foam drainage tests in deep gas wells, increasing the output of natural gas by more than 35,000 cubic meters per day, which provided technical support for the stable production of low-yield gas wells in Daqing. The head of Daqing Gas Branch Geological Technology Institute said foam drainage technology is to inject effervescent liquid into the gas well where fluid is accumulated in the wellbore. With the stirring effect of natural gas flow, it is well mixed with the bottom hole effusion to produce a large amount of comparison Stable aqueous foam
