摘要
为更好地开发利用湖南煤层资源,根据《新一轮全国油气资源评价》方案计算了湖南煤层气资源量、可采资源量和资源丰度,并探讨了其分布特征。经计算汇总,湖南煤层气地质资源量和可采资源量分别为780.80×10^8m^3和325.94×10^8m^3,煤层气资源丰度为0.30×10^8m^3/km^2。煤层气风化带-1 000m和1 000～1 500m的煤层气资源量分别为489.81×10^8m^3和290.99×10^8m^3。湖南煤层气资源主要分布在下石炭统测水组和上二叠统龙潭组中,分别为317.13×10^8m^3和463.67×10^8m^3,其中,下石炭统测水组煤层气资源主要分布在涟邵目标区的渣渡、金竹山、太平寺、冷水江等含煤向斜区域,上二叠统龙潭组煤层气资源主要分布在郴耒目标区的永耒、梅田、白沙、马田等含煤向斜区域。
To develop and utilize the coalbed methane （CBM） resources in Hunan, CBM resource, recoverable resource and resource abundance were Estimated based on the latest national hydrocarbon resource assessment scheme, and distribution characteristics of CBM resource discussed. The results showed that CBM resource and recoverable resource in Hunan are 780.80×10^8m^3 and 325.94×10^8m^3 respectively, resource abundance is 0.30×10^8m^3. The CBM resource from the base of weathering zone to 1000m and from 1000 to 1500m are 489.81×10^8 and 290.99×10^8m^3 respectively. The CBM resource in Hunan is mainly concentrated in the Ceshui Formation of the Lower Carboniferous Series （317.13×10^8m^3） and the Longtan Formation of the Upper Permian Series （463.67×10^8m^3）. CBM resource in Lower Carboniferous Series is mainly concentrated in the coal-bearing synclines of Zhadu, Jinzhushan, Taipingsi and Lengshuijiang in the Lianshao target area, and CBM resource in Upper Permian Series is mainly concentrated in the coal-beating synclines of Yonglei, Meitian, Baisha and Matian in the Chenlei target area.
