沁水盆地樊庄区块煤层气资源与探明储量

Coal-bed methane resources and proved reserves in Fanzhuang Block of Qinshui Basin

应用含气量法对沁水盆地樊庄区块主要目标煤层的煤层气资源量和探明储量进行了计算。通过采用块段划分、平均取值、统一求和的研究方法,得出结论为:该区块煤层气资源丰富,总资源量达735.32×108m3,资源丰度大,为2.32×108m3·km2;煤层气探明储量高,3号、15号煤层累计探明储量349.05×108m3,累计探明可采储量174.53×108m3。研究结果表明,该区块的煤层气资源量和探明储量之大,在我国尚属首例,可以称之为煤层气高富集区。

The coal-bed methane（CBM） resources and proved reserves of main target coal seams in Fanzhuang Block of Qinshui Basin are calculated by using gas content method. Methods of block dividing, average valuing and unified summation are used in the research. It is concluded that CBM resources is abundant in the block, which is totally 735.32×10^8m^3. The abundance of resources is great, which is of 2.32×10^8m^3/km^2 .The proved reserves is high and the proved reserves of 3# and 15# coal seams are accumulated to 349.05×10^8m^3, and their proved recoverable reserves is accumulated 174.53×10^8m^3. Results show that the huge CBM resources and proved reserves of the block are in the first place in China ,which can be called high abundant area of CBM.
