The Analysis of Heat Storage Capacity and the Formation Characteristics of Geothermal Resources in Sedimentary Basins —— A Case Study on Dunhuang Basin
نویسندگان
چکیده
The geothermal resources in sedimentary basin are affected by many factors because the characteristic of geothermal reservoirs is very complex, so the heat storage capacities are hard to calculate. This paper took Dunhuang Basin as an example to analyze the geological structure, stratigraphic structure and the formation mechanism of geothermal water based on the formation characteristics of the geothermal resources. The analysis results showed the geothermal reservoir parameters, including the area, thickness and temperature of the geothermal reservoir and porosity, etc. Based on geothermal reservoir model, the conclusion was that the geothermal resource of Dunhuang basin was 7.75E+16kJ. The results provided an advice for the exploitation of geothermal resources in sedimentary basins.
