分析研究了云南富源富煤二矿的煤层特征、含气特征、吸附特征、煤层气资源特征,并采用数值模拟手段、COMET2模拟软件,对主要可采煤层的产气情况进行了预测。综合分析认为,富煤二矿具有较好的煤层气成藏条件和开发地质条件,煤层气井具有较好的产气效果,开发前景较好。研究成果可为今后富煤二矿的地面煤层气开发,以及煤矿瓦斯治理提供一定的技术支撑和参考价值,同时也表明地质分析与数值模拟相结合是煤层气开发潜力评价的重要手段。
The coal seam characteristics, gas characteristics, adsorption characteristics and CBM resource characteristics of Fuyuan No.2 Coal Mine in Yunnan Province were analyzed and studied. The gas production of the main recoverable coal seams was predicted by using numerical simulation software and COMET2 simulation software. Comprehensive analysis shows that the second coal mine has better CBM formation conditions and the development of geological conditions, CBM wells have good gas production, development prospects are better. The research results can provide some technical support and reference value for the development of coalbed methane on the ground and the management of gas in coal mines. It also shows that the combination of geological analysis and numerical simulation is an important means to evaluate the potential of CBM development.
