Numerical simulation study on evaluation of underground hot water resources
As a kind of clean and environmental protection energy,geothermal demand from all industries is increasing.Taking the area of Neihuang Uplift(Weihui-Huaxian section)as the research object,the temperature gradient of geothermal resources was studied,using the FEFLOW software,numerical simulation and calculation and evaluation of the mining output of geothermal fluid,it was found that the recoverable amount of neene geothermal fluid in the Neogene system in the whole area was 8.39 × 107 m3/a,and the geothermal flu-id recoverable amount of Cambrian-Ordovician thermal reservoir was 2.31 × 106 m3/a;the total geothermal fluid production capacity of the whole region was 303 896.76 kW,which belongs to a large geothermal field,and the annual available thermal energy in the survey area was 1.05 × 1016 J.The research provides scientific basis for the development,utilization and development of geothermal resources in the working area.
