通过河东煤田煤炭、煤层气资源赋存地质条件及地震烈度的综合研究,分别对河东煤田(聚气盆地)保兴含气区、三交北含气区、三交-柳林含气区、石楼含气区、大宁-吉县含气区煤层封存CO2的潜力进行了初步评估,认为该区CO2煤层封存具有一定的潜力和前景.评估结果表明:河东煤田煤层可存储CO2总量为23.93×108 t.依据CO2封存区块适宜性评价指标体系及评价公式对含气区块CO2煤层地质封存适宜性进行评价,煤层埋深1 000~1 500m,三交-柳林含气区为适宜区,其余含气区为基本适宜区;煤层埋深1 500~2 000 m,三交-柳林含气区、保兴含气区为适宜区,其余含气区为基本适宜区.%Based on comprehensive studies on coal, CBM resources hosting geological condition in the Hedong coalfield and earthquake intensity, carried out coal seam CO2 sealing potential preliminary evaluation in the Baoxing, North Sanjiao, Sanjiao-Liulin, Shilou and Daning-Jixian gas-bearing areas in Hedong coalfield (gas-bearing basin) have considered that certain potential and prospect in the ar-eas. The evaluated result has shown that in coal seams in the coalfield possesses total CO2 amount of storage is 23.93×108 t. On the ba-sis of CO2 sealing block suitability evaluation index system and evaluation formula carried out evaluation on gas-bearing block coal seam CO2 sealing suitability, considered that within coal seam buried depth 1 000~1 500 m, the Sanjiao-Liulin gas-bearing area is suitable area, others are basically suitable areas;within 1 500~2 000 m, Sanjiao-Liulin and Baoxing areas are suitable areas, others are basically suitable areas.
