In recent years, a large number of coal- bed methane field pipeline networks have started construction.The advantages and disadvantages of the design scheme of the coal-bed methane gathering and transportation network will have a greater influence on the eco-nomic development of coal-bed methane.At present,the evaluation of the design scheme is based on one of the following index such as reliability,adaptability,and economy.The com-prehensive evaluation of the design scheme of the coal-bed methane field pipeline network is rare. Based on the reference of existing single index evaluation, a coal-bed methane pipe-line network comprehensive evaluation model was built by setting a rating criteria and deter-mining the evaluation index weights.Thus,the preferred and economical scheme can be se-lected by quantitative evaluation to achieve the purpose of economic development of coal-bed methane field.%近年来，我国大量煤层气田管网开始新建或扩建。煤层气集输管网设计方案的优劣会较大程度影响煤层气田开发的经济性。目前针对设计方案的评价多是基于可靠性、适应性、经济性等单一指标进行的，对煤层气管网设计方案综合评价的研究较少。本文在参考现有单个指标评价研究的基础上，通过制定评分等级标准与确定评价指标权重来建立煤层气管网综合评价模型，以定量评价、优选煤层气管网设计方案，达到经济开发煤层气田的目的。
