摘　　要：地面煤层气的开发过程非常复杂,除了受地质条件影响外,钻井、完井工程属性以及排采制度很大程度上影响气井的产量。已有的开发实践证实,煤储层水力压裂改造是煤层气增产的主要手段之一。通过分析已有煤层气的压裂工程属性特征,揭示压裂效果对煤层气产能的影响关系,对下步制定煤层气开发方案或低产低效井治理具有重要的指导意义。The development process of surface coalbed methane is very complex. In addition to the influence of geological conditions, the drilling and completion engineering properties and drainage system greatly affect the production of gas wells. The existing development practice has proved that hydraulic fracturing of coal reservoir is one of the main means to increase the production of coalbed methane. By analyzing the characteristics of fracturing engineering properties of existing coalbed methane, it has important guiding significance to formulate coalbed methane development plan or to treat low production and low efficiency wells in the next step.
