摘要
产气量较低的煤层气井实施解堵性二次压裂后,需要通过精细排采管控,稳步降低流压才能有效提高单井产能。本文通过梳理近年沁水盆地南部樊庄-郑庄区块解堵性二次压裂井的实施情况,总结现场实施要点、排采管理方法,有利于提高现场实施效率,为煤层气低产井增产方案的高效实施提供借鉴。
After application of plugging secondary fracturing to low-recovery coalbed methane well, the fluid pressure is stably reduced by fine production and control to effectively enhance the single-well pro- ductivity. Based on the plugging secondary fracturing in Fanzhuang-Zhengzhuang Block in South Qinshui Basin in recent years, the plugging secondary fracturing, production and control management methods are summarized to enhance the field efficiency and give a reference to efficient implementation of en- hanced recovery from low-recovery coalbed methane well in this paper.
