抚顺煤层气赋存特征及资源评价研究

抚顺矿区城市下压煤面积6km^2，煤炭储量23901．5万t。通过对矿区地质特征、煤储层特征分析．认为区内煤层气含量高（9．81～24．53m^3／t），煤层中大空隙多，透气性好，渗透率较高（0．24～3．60mD）。煤层直接顶板为厚100m左右的致密油页岩，底板为泥岩、凝灰岩，具有良好的封闭条件。根据矿区多年测试资料，采用容积法得出区内煤层气资源量为30．53亿m^3。综合开发煤层气资源符合东北老矿区的实际，其将为复苏东北重工业基地提供有效的洁净能源。

A Study on CBM Hosting Features and Resource Evaluation in Fushun

There is 6km^2 of coal block under the urban Fushun mining area with 239.015 million tons of coal reserves. Through analyses of mining area geological features and coal reservoir characteristics, considered that CBM in the area has high content （9.81～24.53m^3/t）, quite a number of macropores, good gas permeability and rather high permeability （0.24～3.60m/d）. Coal seam immediate roof is lOOm thick compact oil shale, floor are mudstone and tuff all provided with good sealing conditions. Based on mining area testing data of many years, by the use of volumetric method, estimated CBM resources in the area is 3.053 billion m^3. Comprehensive development of CBM resources is truthful to the renaissance of the Northeast China old mining area and will provide clean energy for the heavy industry base.
