【摘要】 为了对比评价六盘水煤田、织纳煤田、黔北煤田的煤层气开发潜力,以上述3个煤田为研究对象,分析了其构造特征、煤系地层及煤层发育特征、煤储层特征、煤及煤层气资源量,指出了物质基础和生气条件的差异性。研究结果表明:六盘水煤田煤层气资源量为13 895.26×10~8m~3,煤层气平均资源丰度为2.26×10~8m~3/km~2,煤层气勘探程度最高;织纳煤田煤层气资源量为7 002.80×10~8m~3,煤层气平均资源丰度为1.41×10~8m~3/km~2,煤层气勘探程度较高;黔北煤田煤层气资源量为7 392.15×10~8m~3,平均资源丰度为0.66×10~8m~3/km~2,但煤层气勘探程度较低。结论认为,六盘水煤田开发潜力最大,织纳煤田开发潜力较高,黔北煤田开发潜力最小。更多还原

【Abstract】 In order to compare and evaluate the development potential of coalbed methane(CBM) in Liupanshui,Zhi’na, and Qianbei coalfields, Guizhou Province, this study took these three fields as examples, and analyzed their structural and development characteristics of coal-bearing strata and coal beds, reservoir characteristics, and coal and CBM resources, and pointed out the difference between their material base and gas-generating conditions. It is found that in Liupanshui Coalfield, there are CBM resources of 13 895.26 × 10~8 m~3, with average resource abundance of 2.26× 10~8 m~3/km~2, and its CBM exploration degree is the highest; in Zhi’na field, CBM resources of 7002.80 × 10~8 m~3, average resource abundance of 1.41 × 10~8 m~3/km~2, and higher CBM exploration degree; and in Qianbei field, CBM resources of 7392.15 × 10~8 m~3, average resource abundance of 0.66 × 10~8 m~3/km~2, and lower exploration degree. In conclusion,the development potential of Liupanshui field is the greatest, followed by Zhi’na field, and that of Qianbei field is the least.更多还原
