    Abstract
  • The Gonghe Basin is rich in hot dry rock geothermal resources. In order to enhance the theoretical understanding of the genesis of hot dry rock geothermal resources in the Gonghe Basin and further promote the exploration of hot dry rock resources, a comprehensive analysis of the genesis of hot dry rock resources in the Gonghe Basin is made from the heat source mechanism, caprock conditions and reservoir characteristics. Firstly, combined with regional geological structure analysis, geothermal geological survey, geophysical (aeromagnetic, earthquake) interpretation, four hot dry rock exploration wells with the depth of 2927-3705 m were drilled in the Gonghe Basin. At 3705 m, the high-quality hot dry rock resources of 236℃ were obtained, which was the first major breakthrough in the exploration of hot dry rock geothermal resources in China's non-modern volcanic areas. Secondly, radioactivities of granites from different depths were tested. The results show that the radioactive elements content of U, Th and K in the granitoids of the Gonghe Basin is slightly higher than the background value of the earth, and the radioactive heat generation rate is relatively low, the contribution of radioactive heat to the heat source of hot dry rock is less and the heat source may come from the melt in the Crust. Thirdly, based on geological data analysis and aeromagnetic interpretation, the potential hot dry rock distribution area of the Gonghe Basin is about 1.4×104 km2. Finally, the volumetric method is used to evaluate the potential of hot dry rock resources in the Gonghe Basin. The results show that the total conservative and static amount of hot dry rock resources in the 3.0-6.0 km range of the Gonghe Basin is 8974.74×1018 J, and the converted standard coal can reach 306.619 billion tons, showing the broad prospects for development and utilization.
