Abstract:

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 comprehensiveresearch about the geological conditions of CO2 sequestration in coal seams，the preliminary assessments of the storage potentialare made for the coal fields in southern Jiangsu，Xuzhou and Fengpei，respectively. The results show that the coal seams in thesecoal fields have considerable potential and disposal prospect for CO2 sequestration. The estimate of CO2 storage resources in coalseams in Jiangsu Province is over three hundred million tons of CO2. Among these coal seams，southern Jiangsu coal area couldsequester 81 million tons of CO2，Xuzhou coal area of nearly 150 million tons of CO2 and Fengpei coal area of 87 million tons ofCO2. 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).
