摘　　要：煤层CO2地质储存是CCS中的四种技术方案之一,是减少CO2排放的有效方式。根据最新一轮全国煤层气资源调查的含煤层气盆地煤层气可采储量结果,基于碳封存领导人论坛（CSLF）推荐的计算方法进行我国主要煤田CO2地质储存潜力评价,计算了我国埋深在1000~2000m内煤层的CO2地质储存潜力,计算结果表明全国28个含煤层气盆地煤层储存CO2总潜力为9881×10^8t。其中鄂尔多斯盆地、准格尔盆地、吐哈盆地、海拉尔盆地的储存潜力都超过10×108t,这4个盆地的总储存潜力为6845×108t,占全国总储存潜力的6927%,将是我国进行煤田CO2地质储存的主要盆地。According to the latest national CBM resources survey result of coal seam gas recoverable reserves, based on the method for calculating CO2 geological storage potential evaluation in the main coalfields of our country recommended by carbon sequestration leaders forum （ CSLF）, CO2 geological storage potential of the buried depth of coal seam in the 1000-2000m are calculated, the calculated results showed the total potential of coal seam gas of 28 bearing basins in China is 98.81×10^8st. Moreover, the CO2 geological storage potential for each of fourbasins： Ordos basin, Junggar basin, Tuha basin and Hailar basin, is more than ×10^8st. The four basins total storage potential is 68.45×10^8st, accounting for 69. 27% of national total storage potential, and will be the main basin coal field CO2 geological storage in our country.
