REGIONALIZATION OF GEOTHERMAL RESOURCE POTENTIAL IN BEIJING

As an ideal green energy, geothermal resources play an increasingly important role in the world. The geothermal resources in Beijing belongs to low-medium temperature geothermal resources, which is mainly distributed in ten geothermal fields. The focus on geothermal water concentrated development and utilization in Beijing has 40 years history. In order to grasp the development potential of geothermal resources in Beijing, this paper carries out the potential assessment of geothermal resources based on the characteristics analysis of tectonic, the types of geothermal resources and the distribution of geotemperature. Based on the geothermal energy extraction coefficient, the exploitation of geothermal water and the water level deceleration, regionalization of the geothermal resources potential in Beijing is constructed. The geothermal fields are divided into 29 evaluation units and are divided into six zones including serious overdraft area, overdraft area, balance area, low potential area, higher potential area, and highest potential area.
