摘要 强化煤层气采收率的深部煤层封存CO_2技术(carbon dioxide sequestration in deep coal seams with enhanced coalbed methane recovery,CO_2-ECBM),既能减少主要人为温室气体CO_2的排放,又能获得宝贵的煤层气(CH4)资源。作为重要的CO_2地质封存技术,CO_2-ECBM技术成为目前的研究热点。因此,针对CO_2-ECBM技术开展评述工作具有重要的现实意义。针对CO_2-ECBM主要研究结论包括:(1)CO_2-ECBM技术优势及可行性;(2)煤储层条件下,煤体对CH4和CO_2的吸附机理;(3)用于实施CO_2-ECBM的备选煤层的选择标准;(4)CO_2-ECBM后续研究展望。 Carbon dioxide sequestration in deep coal seams with enhanced coalbed methane recovery( CO_2-ECBM) not only can mitigate CO_2 emissions,but also enchance coal-bed methane recovery. As a potential CO_2 geologic option,CO_2-ECBM has been a hot issue. Thus,the review work on CO_2-ECBM is of great significance. This work reviews CO_2 sequestration in deep coal seams with enhanced coalbed methane recovery( CO_2-ECBM). The main conclusions include:( 1) the advantages and feasibility of CO_2-ECBM;( 2) the adsorption mechanism of both CH4 and CO_2 on coal under the actual coal reservoirs;( 3) the selection standard of the coal reservoirs for CO_2-ECBM;( 4) the future study trend of CO_2-ECBM.
