Hierarchical Fuzzy Comprehensive Evaluation for CBM Favorable Areas in Western Guizhou and Eastern Yunnan

Abstract:

In order to select favorable coal bed methane (CBM) areas in western Guizhou and Eastern Yunnan, 5 typical mining areas were used to estimate. Based on physical properties, reservoir capacity and coal geological features, coal reservoirs evaluation model was constructed through hierarchical fuzzy comprehensive evaluation method. The results showed that: coal reservoirs were divided into 4 types, and among them, type I was the best reservoir which was mainly distributed in the western part of Zhina and Gemudi, the southeast of Panguan, and the northern part of Enhong and Laochang.
