摘　　要：本文通过对煤层CH4脱附原理和CO2基本特性的介绍,结合国内设备配套和施工能力, 经过分析和推理,提出利用CO2吞吐、CO2增能压裂和CO2泡沫压裂的可行性。根据我国目前煤 层改造的现状,进一步阐述了应用CO2泡沫压裂对煤层实施强化改造的重要性。建议尽早开展专 题研究,对煤层实施CO2泡沫压裂改造,以提高煤层气产量。This paper introduces the principle of CH4 desorption in the coal seam and basic features of CO2. In light of the support and implementation capacity of China' s current equipment, it proposes the feasibility of the utilization of CO2 huff & puff, CO2 enhanced fracturing and CO2 foam fracturing. According to the current restructuring in our country' s coal seams, it further clarifies the importance of making enhanced restructuring of coal seams by the use of CO2 foam fracturing. It suggests that a special topic research should be performed over the coal seam restructuring with the technology of CO2 foam fracturing in order to increase the recovery of coalbed methane.
