摘　　要：煤层气井产量受控因素较多,经济上存在着较大的风险性。通过分析煤层气井产量的影响因素,优化出13项评价指标,把定性和定量指标进行标准化处理,建立了指标体系。合理设计递阶结构模型,采用层次分析法进行定量评价,形成了一套完善的煤层气井评价方法和体系。通过晋城、韩城矿区实际资料的应用,效果良好,为煤层气高产井的部署和实施提供了依据。There are many factors controlling CBM well production and relatively high economic risk. Through the analysis of the influencing factors on production of coalbed methane wells, 13 indexes are optimized. By standardi-zing the qualitative and quantitative indexes, the index system is established. With the reasonable designation of hierarchical structure model and usage of analytic hierarchy process for quantitative evaluation, a set of perfect evaluation method and system of coalbed methane wells is formed. The application of practical data in Jincheng mining area has produced good results. The research results provide a basis for the improvement of success rate of highly productive coalbed methane wells and optimizing production measure.
