Abstract:

As a clean renewable energy, geothermal energy has played an important role in improving the atmospheric quality of Beijing. This study evaluates the geothermal resource in the Changping New Town, Beijing, and provides scientific basis for rational utilization of geothermal resource in this area. After analyzing the geological and geothermal conditions in the study area, we built a 3D geological model of the Changping New Town, which is used to calculate the volume of reservoirs,then the geothermal reserve is calculated with the volumetric method, and the geothermal resource distribution is analyzed. 3D geological modeling is used to visualize the local geological structures and calculate the geothermal reserve. The estimated reservoir volume in the study area is 4.88×1011 m3 and the geothermal reserve is 5.42×1016 kJ. The exploitable volume of geothermal fluid is 6.04×106 m3. The geothermal resource in the study area is likely of great potential, and can support locally green development.

Key words: Changping, 3D geological modeling, geothermal resource, volumetric method
