摘　　要：针对煤层气钻井工程项目中的危险因素以及可能发生的钻机工程项目事故的特征,需要利用科学的方法,建立适合煤层气钻井工程项目特点的风险评价体系。本文采用模糊层次分析法,评价煤层气钻井工程项目风险。通过确定煤层气钻井工程项目风险指标体系,运用层次分析法得到其权重,并采用经济学中的ABC分类法,对风险因素进行分类,确定出重点管理的风险因素及一般管理的风险因素。利用风险隶属矩阵,多因素模糊层次评判,采用加权平均法,确定最终结果,计算出山西晋城寺河矿煤层气钻井工程项目的总体风险值为4.1,属于风险很大的一类。This paper, aiming at the dangerous aspects and potential accidents in coal-bed methane drilling projects, establishes a risk assessment system. The FAHP has been applied to assess the risks in coal-bed methane drilling project. The risk index system is defined through drilling projects, and assigned with weights by means of AHP. The risks are classified as key risks and common risks via the ABC classification method in economics. This method has been used to calculate the risk value in Sihe coal-bed methane drilling project, Jineheng, Shanxi province. The value is 4. 1, meaning of big risk.
