煤层气产能潜力模糊数学评价研究——以河东煤田柳林矿区为例

CBM Potential Productivity Assessment through Fuzzy Mathematics——A Case Study in Liulin Mine Area, Hedong Coalfield

在系统分析影响煤层气产能潜力开发地质因素的基础上,确立了以二级评价指标地质储量参数和开发参数为支撑的煤层气产能潜力模糊评价体系及对应的三级评价指标,采用模糊数学方法对各评价指标进行了权重赋值,建立了用于煤层气产能潜力评价模糊数学评价模型。利用该模型,对河东煤田柳林矿区的煤层气产能潜力进行了评价,认为该矿区3-5#煤层煤层气产能潜力较大,为该矿区煤层气开发的有利层段。

Based on the CBM potential productivity geological influencing factor systematic analysis, established a potential productivity fuzzy assessment system and corresponding third order assessment indices supported by second order assessment index geologic reserve parameters and exploitation parameters. To use fuzzy mathematics carried out weight assignment to each assessment index, established a fuzzy mathematic assessment model for CBM potential productivity assessment. To use the model assessed CBM potential productivity in the Liulin mine area, Hedong coalfield, and considered that the No.3-5 coal seam in the mine area has better productivity potential, thus a beneficial sector in the area.
