中国煤层甲烷可采资源量及当前主要勘探区

Recoverable reserves and major present exploration region of coalbed methane in China. SOGR

方法通过分析中国煤层甲烷的资源构成，同时考虑资源品位、地质、开发条件等因素的影响，估算出中国煤层甲烷当前可采资源量。目的指出中国煤层甲烷的主要勘探区及近期大规模勘探开发的区域。结果中国煤层甲烷当前可采资源量为10×10^(12)m^3左右，其中华北地区约6×10^(12)m^3，西北地区约3×10^(12)m^3。结论华北、西北地区是中国煤层甲烷的主要勘探区；而华北地区C—P煤系为近期大规模勘探开发的主要目标。

Method To evaluate present recoverable reserves of coalbed methane in China by analyzing resource components of methane in coal seams,as well as considering resource grade, geological and development conditions. Purpose To determine major coalbed methane exploration region in China and the regions for large scope exploration and development at present time. Result The present recoverable reserves of Chinese coalbed methane is about 10×1012 m3. There is about 6×1012 m3 in north China and 3×1012m3 in northwest China. Conclusion Major exploration region of Chinese coalbed methane are north and northwest China; while the target region for large scope exploration and development at present time is Carboniferous-Permian coal measures of north China.
