摘　　要：煤层气资源可采性评价是煤层气勘探开发的前提和基础。针对煤层气资源勘探开发的实际情况及目前煤层气开采的技术水平,基于模糊数学理论,在系统分析影响煤层气可采性主要储层地质参数、储集参数和物性参数等的基础上,建立了煤层气资源可采性评价指标体系,确定了评价参数隶属函数矩阵修正系数的方法,提出了煤层气可采性量化综合评价方案;并以阜新煤田为例,进行了煤层气可采性的综合评价。评价结果与实际情况较一致。Assessment of recoverability of coalbed methane resources is the prerequisite and basis of exploration and production.In view of the status of exploration and production of coalbed methane and the current technical level of coalbed methane recovery,fuzzy mathematics theory is used to systematically analyze those parameters including the geologic features,reservoirs and physical property,an index system for assessment of recoverability of coalbed methane resources are established,methods for determining correction coefficient of membership function matrix of the assessment parameters are proposed,and a comprehensive assessment program of coalbed methane recoverability is presented.A case study of the Fuxin coal field shows that the results of comprehensive evaluation of coalbed methane recoverability basically accord with the reality.
