摘要
介绍了体积压裂与速度管柱排液复合技术在气井修复中的应用,以及体积压裂后一边放喷排液一边安装速度管柱的流程。气井进入开采后期,地层能量降低,产水量增加,产气量降低,采用连续油管做速度生产管柱,减小了流体流动面积,增大了流体流速,在极短的时间内大幅度提高了排液效率和排液能力,使气井恢复生产。
In this article, it introduced the application of volume fracturing and velocity string discharging fluid composite technology in gas well repair, as well as work flow, after volume fracturing, it discharges fluid while fitting velocity string. When gas well enters into late stage of exploiting, the stratum energy decrease, water production increase, gas production decrease. Adopting coiled tubing to act as velocity string, which decrease fluid area, increase fluid speed, and greatly enhance efficiency and capability of discharging fluid, make gas well resume production.
