为了评价鹤岗盆地煤层气的资源潜力,从煤层气的成藏条件出发,将鹤岗盆地相关的地质、地化参数与阜新盆地进行类比,采用模糊数学方法对两个盆地资源潜力进行评分,并计算出鹤岗盆地煤层气资源总量.结果表明,鹤岗盆地绝大部分地质、地化指标相似于甚至优于阜新盆地;鹤岗盆地煤炭资源丰富,煤阶以气煤—焦煤为主,煤层累计厚度平均64 m,为煤层气的大量生成提供了良好的物质基础.但是,由于岩浆和构造活动以及有效盖层的差异,使不同矿区含气量差别较大,整体表现为东北高、西南低的特征.尽管鹤岗盆地部分煤层含气量和渗透率偏低,但其煤层分布规模大,煤阶中等,其煤层气资源总量可达445.6×108 m3,通过合理开采,可具有较大的工业产能.

In order to evaluate the resources potential of coalbed methane in Hegang basin, this paper analyzes the formation condition of the coal bed, an analogy has been made between the geological and geochemical parameters in Hegang basin and those in Fuxin basin, the paper also grades the resources potential of CBM in two basins and calculates the resources extents of Hegang basin. According to the evaluation results, most of the geological and geochemical parameters are similar to those of Fuxin basin, some of them are even better. Hegang basin is rich in coal resource, and most are medium and low coal ranks. The average coal thickness is 64 m, provides a good con-dition for the formation of CBM. As the magmatic activities, tectonic movement and the effectiveness of the cover vary in different mining area, the gas content in northeast areas is higher than that in southwest areas. although the gas content and permeability are low in some mining areas, the distribution area of the coal bed is large and most of the coal is in medial rank, CBM reserves is 445.6×108 m3 which can create large industrial production by rational exploitation.
