高压高产气井放空天然气回收技术
|
摘要
2015年实施措施前,库车山前试油期间测试放喷天然气全部放空燃烧,累计放空燃烧量超7000×104m3,浪费资源又污染环境,不符合节能减排和绿色环保的要求。为了实现放空气回收实现零排放,坚持安全绿色环保发展,持续提升放空气回收新技术研究,经过3年的攻关,形成了适合高压高产气井的放空气高压分离回收技术,并积极推进测试气回收新工艺"高压分离回收技术"的应用。2016年至2017年度利用高压分离技术开展20井次放空气回收,共回收天然气4.37×108m3,减少碳排放量75.15×104t,节约标煤28.68×104t,实现节能减排。
Before the implementation of the measures in 2015, during the pre-test period of Kuqa mountain, all the gas released and injected was tested and burned in the air, with an accumulative amount of 7 000 × 104 m3,which wasted resources and polluted the environment, and did not meet the requirements of energy conservation, emission reduction and environmental protection.In order to realize the zero discharge and release of the reentrant air, we should stick to the safe green ring for development, and continue to carry out the research on the new technology of reentrant air recovery.From 2016 to 2017, the high-pressure separation technique was applied to open 20 Wells of secondary air release to recover, and a total of 4.37×108 m3 of natural gas was recovered. The carbon emission was reduced by 75.15×104 t,and the standard coal was saved by 28.68 ×104 t to realize energy saving and emission reduction
