| 摘 要： | 煤层气含气区带综合评价是一个多因素、多层次、多目标的决策过程，其评价过程受到诸多因素的影响，需要选择科学、简捷、实用的数学模型来分析处理这些繁杂因素。因此，根据煤层气含气区带综合评价涉及的各种因素建立评价指标体系,并结合层次分析法和灰聚类分析各自的优点，建立煤层气含气区带综合评价模型。应用层次分析法确定各指标的权系数，然后通过灰聚类分析法来进行综合评价，较好地保证了权系数的客观性和准确性，定性、定量地对煤层气含气区带进行综合评价。可以为整个煤层气行业的资源综合评价奠定基础，同时通过评价案例进行了验证。评价结果表明，全国121个煤层气含气区带中，最有利区带是沁水盆地和鄂尔多斯盆地东缘，有利区带为鄂尔多斯盆地南缘、宁武、安阳-鹤壁和松藻地区。

| Abstract: | Comprehensive evaluation of coalbed methane zone is a complex system,which is controlled by multi-factors and is difficult to estimate.This paper proposes an index system of evaluation based on correlated factors involved in coalbed methane zone and a comprehensive evaluation model that combines the advantages of the AHP and a grey clustering method to guarantee the accuracy and objectivity of weight coefficients.First,the weight of every index is confirmed using the AHP,then a comprehensive evaluation is done by a grey clustering method.In this way,it improves and generalizes some known evaluation methods.An example to illustrate the application of the theoretical results is given.The results show that the method is applicable and realistic with regard to the comprehensive evaluation.In 121 coalbed methane zones in China,Qinshui Basin and the east margin of Ordos Basin are most advantaged zones and the south margin of Ordos Basin,Ningwu,Anyang-Hebi,Songzao are comparatively advantaged zones. |
