摘　　要：开发后期气井面临压力系数大幅度降低、生产状况复杂,压裂改造难度增加等一系列问题,根据文23气田实际情况探讨了开发后期压裂的难点,并给出了相应的配套压裂方法,这些技术在实践中取得了成功。In production tail of gas reservoirs, the formation pressure is reduced greatly. The production status becomes complicated. So, its difficulties of fracturing were increased. On the basis of the actual problems existent in Wen 23 gas field fracturing,proposed corresponding support fracturing methods which included fracturing technology of low pressure well ,separate layer fracturing technology, gas well fracturing technology in poor well status and refracturing technology. The technologies have achieved success in field application.

关 键 词：气井压裂 低压力系数 配套技术
