The geological conditions of CO2 sequestration in coal seams in Jiangsu Province contain the distribution of Carboniferous-Permian coal measures,coal resources and coal seam reservoir conditions. According to the comprehensive research about the geological conditions of CO2 sequestration in coal seams, the preliminary assessments of the storage potential are made for the coal fields in southern Jiangsu, Xuzhou and Fengpei, respectively. The results show that the coal seams in these coal fields have considerable potential and disposal prospect for CO2 sequestration. The estimate of CO2 storage resources in coal seams in Jiangsu Province is over three hundred million tons of CO2. Among these coal seams .southern Jiangsu coal area could sequester 81 million tons of CO2,Xuzhou coal area of nearly 150 million tons of CO2 and Fengpei coal area of 87 million tons of CO2. The prospect of typical coal-seam CO2 sequestration can be divided into three categories : suitable storage area( Class A), less suitable storage area ( B), and poor storage area ( Class C).%根据江苏省石炭—二叠纪煤系的分布、煤炭资源量和煤层的储集条件等煤封存CO2地质条件的综合研究,分别对苏南煤田、徐州煤田、丰沛煤田煤层封存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.评估结果表明江苏省煤层可存储CO2总量超过3×108t,其中苏南含煤区可存储CO2容量为8.1×107 t,徐州煤矿区可存储容量近1.5×108t,丰沛煤矿区为8.7× 107t.并对各典型含煤区块CO2煤封存前景进行分类:适合存储区(A类)、较适合存储区(B类)和较差存储区(C类).
