Assessment of the suitability of geological storage of CO2 according to geothermal conditions of sedimentary basins in China
摘要
Abstract
Geological storage of CO, is one of the mean measurements for avoiding the release of anthropogenic C02 into the atmosphere, which may prevent the global temperature rising. At present, the geothermal regime is one of the most important factors for the suitability assessment. However, the rationality of geothermal reign needs to be improved. This paper assesses the geothermal suitability of C02 storage with the weighting method, using geothermal gradient, terrestrial heat flow and surface temperature. The results show that 2. 1% (8. 5 x 104km2) of sedimentary basins are the most suitable for CO2 geological sequestration, 68.6% (274.0 x 104 km2) are better suitable, 24. 6% (98. 4 x 104km2) are suitable, 4. 7% (18. 7 x 104km2) are less suitable. However, the worst suitable sedimentary basins have not been found. The results improve the accuracy of geothermal conditions for the suitability assessment of CO2 storage.关键词
