基于组合权重的煤层气有利区块模糊优选

为优先对黔西-滇东煤层气聚气区内有利含气区块进行开发，以6个代表性煤层气区块为研究对象，选取储层因素、资源因素和开发因素3方面9项指标构成评价矩阵，运用灰关联分析和层次分析法建立组合权重向量，通过多层次多目标模糊优选模型对研究区进行优选排序，并通过专题地图反映优选结果。结果表明，最优目标区块是织纳煤田，较优目标区是盘县、老厂、六枝和水城矿区，恩洪矿区则为一般目标区。

Fuzzy optimization for CBM favorable targets based on combined weights

To optimizing coalbed methane(CBM) favorable targets in western Guizhou Province and eastern Yunnan Province,six typical areas were focused on to estimate which should be explored preferentially.Firstly,nine parameters in three categories,e.g.the coal reservoir,the resource conditions and the exploitation infrastructures were concentrated to form an evaluation matrix.Subsequently,the matrix was weighted by a vector that combined the grey correlation analysis and the analytic hierarchy process(AHP) and was calculated in a fuzzy multi-objective and multi-level optimization model.Finally,the results of the calculation were drawn on a thematic map.It indicate that the optimal target is the Zhina Coalmine,and the Panxian Coalmine is suboptimal as well as the Laochang,Liuzhi and Shuicheng Coalmines.By contrast,the Enhong Coalmine is unfavorable.
