Abstract As a renewable clean energy，geothermal energy has a great potential development. Using CO2 to enhance the geothermal recovery with simultaneous sequestration of carbon is a novel approach. The integration technology of two current main types(hot dry rock and hydrothermal) of geothermal recovery technology with simultaneous sequestration of carbon is analyzed. Then as for the specific geological conditions of a saline aquifers CCS(CO2 capture and storage) site in the northwest of China，the flow efficiency/pressure change of CO2 and water between the production and injection wells under the same conditions are compared. Moreover，the heating extraction rates of water/CO2 under two different kinds of reservoir conditions are calculated，and then the corresponding amount of carbon sequestration，safety and economic feasibility are analyzed. These results show that CO2 is superior to water in its ability to heat exploitation from the hot reservoir. Therefore，using CO2 to enhance the geothermal recovery with simultaneous sequestration of carbon has a strong feasibility in China.
