清镇市新店西二勘查区煤层气资源评价

CBM Resources Evaluation of Xindian West Ⅱ Exploration Area in Qingzhen City

根据勘查区煤田地质钻孔勘查资料及煤层气参数井获得的详实资料,对新店西二勘查区煤层气资源量进行了估算和预测。区内主采煤层主要为中灰~中高灰、中高硫~高硫、中发热量~高发热量、特低挥发分煤。区内煤层气总资源量7.24×10~8m^3,其中9号煤层为4.81×10~8m^3,13煤层为2.43×10~8m^3;煤层气资源丰度为0.19×10~8m^3/km^2,本勘查区内煤层气储量规模为小型,其煤层气资源储量丰度特低。

Based on the exploration materials of geological boreholes and detailed materials obtained by the CBM parameter wells, the paper estimates and predicts the CBM reserves in the Xindian West Ⅱ Ex- ploration Area. The main production coal seams within the area mostly contain with medium to mid-high ash content, mid-high and high sulfur content, medium to high calorific value and extremely low volatile matter. The total CBM reserves reaches 7.24 × 108m3 with 4. 81 ×108m3 stored in No. 9 coal seam and 2.43 × 108m3 in the No. 13 coal seam, and the CBM resources abundance is 0. 19 × 108m3/km2. It is es- timated that the reserve scale of CBM in this area is small with extremely low resources abundance.
