强化煤层气采收率的深部煤层封存CO2技术(CO2-ECBM)进展研究

强化煤层气采收率的深部煤层封存CO2技术(carbon dioxide sequestration in deep coal seams with en-hanced coalbed methane recovery,CO2-ECBM),既能减少主要人为温室气体CO2的排放,又能获得宝贵的煤层气(CH4)资源.作为重要的CO2地质封存技术,CO2-ECBM技术成为目前的研究热点.因此,针对CO2-ECBM技术开展评述工作具有重要的现实意义.针对CO2-ECBM主要研究结论包括:(1)CO2-ECBM技术优势及可行性;(2)煤储层条件下,煤体对CH4和CO2的吸附机理;(3)用于实施CO2-ECBM的备选煤层的选择标准;(4)CO2-ECBM后续研究展望.

Carbon Dioxide Sequestration in Deep Coal Seams with Enhanced Coalbed Methane Recovery( CO2-ECBM):a Review

Carbon dioxide sequestration in deep coal seams with enhanced coalbed methane recovery( CO2 -ECBM) not only can mitigate CO2 emissions, but also enchance coal-bed methane recovery. As a potential CO2 geologic option, CO2 -ECBM has been a hot issue. Thus, the review work on CO2 -ECBM is of great significance. This work reviews CO2 sequestration in deep coal seams with enhanced coalbed methane recovery(CO2 -ECBM). The main conclusions include:(1) the advantages and fea-sibility of CO2 -ECBM;(2) the adsorption mechanism of both CH4 and CO2 on coal under the actual coal reservoirs;(3) the se-lection standard of the coal reservoirs for CO2 -ECBM;(4) the future study trend of CO2 -ECBM.
