| 摘 要： | 通过分析研究山西省沁水煤田的煤层气地质条件和储层特征,结合煤层气开发试验结果,对无烟煤等高煤级煤的煤层气资源开发潜力进行了评价。结果表明:无烟煤等高煤级煤只要煤储层特征参数组合匹配良好,尤其是在较简单的构造条件下,煤体结构完整,煤中裂隙网络较发育且保存较好,煤储层渗透率较高,煤层气资源开发就具有良好的前景。

| Abstract: | The CBM geological conditions and reservoir characteristics in the Qinshui coalfield,Shanxi are researched.Based on the research results,CBM potential of high rank coals such as anthracite and so on are evaluated.The results indicated that high rank coals may have the good potential of CBM development,when coal reservoir parameters are well combined,especially the permeability is good.The permeability of high rank coal is mainly contributed to the well preserved coal fracture network caused by structure in a suitable geological tectonic background. |
