摘　　要：煤层气井压裂与油气井压裂相比有很大的区别,煤层气井压裂一直存在着煤层割理系统发育、滤失严重、施工难度大的问题。为解决这一问题,对煤层压裂液进行了优化,对压裂技术进行了改进。经阜新刘家区4口井的现场应用,压裂效果显著,该4口井投产后稳产期平均单井日产量在3000m3/d以上,最高单井日产量超过6000m3/d。Fracturing of coalbed methane wells is quite different from that of oil and gas wells. Such problems as developed cleats system, serious loss, and difficult operation are always there during CBM well fracturing. To solve the problem, the Coalbed Methane Development Company of Liaohe Petroleum Exploration Bureau has optimized the fracturing fluids and improved the fracturing technology. After applying the said technology to four wells in Fuxin Liujia Area, remarkable results have been made. The average gas production per unit well has exceeded 3,000m^3/d, with the highest more than 6,000m^3/d.
