| 摘 要： | 对影响煤层气勘探开发潜力的各种因素进行了综合研究，确定了煤层气勘探开发潜力评价的3个二级指标(生气潜力、储层物性和封盖性能)及对应的三级指标。采用模糊数学方法对各级因素指标赋予权重，建立了用于煤层气勘探开发潜力评价的多层次模糊数学评判模型。利用该模型，对青海木里煤田中低煤阶煤层气资源勘探开发潜力进行了评价,认为江仓矿区是木里煤层气勘探开发的最佳试验区。所建立的评价体系可以作为中低煤阶煤层气资源开发潜力评价的参考体系。

| Abstract: | The influencing factors of the coalbed methane (CBM) exploitation potential were investigated in the paper. Three second-order indices, i.e., gas-generation potential, reservoir physical property, sealing capacity, and their corresponding third-order indices for assessment of the CBM exploitation potential were established. The weight values of all second and third-order indices were determined by the fuzzy mathematics, and the multi-layered fuzzy mathematic model for assessment of the CBM exploitation potential was set up. As a case study, the multi-layered fuzzy mathematic model was applied to the assessment of exploration and development potential of the mid-low ranked CBM in the Muli coalfield of Qinghai Province. The results show that the Jiangcang coal mine area has the best potential for CBM exploitation in the Muli coalfield and hence should be the most favorable testing area of the CBM exploitation. The assessment system established in the paper can be regarded as a reference model in the assessment of potential of CBM exploration and development of the mid-low rank coal seams. |
