Abstract: Puyang City has abundant geothermal resources in the middle and deep layers, but the comprehensive utilization and economic benefits of geothermal resources need to be further improved. By collecting and analyzing drilling data from 76 middle and deep geothermal holes and recent exploration and research achievements in Puyang City, the geological distribution, geological structure, hydrogeological conditions, and thermal storage characteristics of the study area are analyzed. The volume method is used to quantitatively calculate the mid to deep geothermal resources in the study area, and an evaluation of favorable areas for geothermal resource development and utilization is carried out. The results show that the suitable thermal reservoirs for development and utilization in Puyang City are mainly the sandstone thermal reservoirs of the Guantao Formation and the Ordovician limestone thermal reservoirs, which contain abundant geothermal resources. Among them, the total geothermal resources of the Guantao Formation thermal storage are 8.67×10¹⁰ GJ and the recoverable resources quantity is 2.17×10¹⁰ GJ, and the total geothermal resources of the Ordovician thermal storage are 9.68×10¹⁰ GJ and the recoverable resources quantity is 1.45×10¹⁰ GJ. The research evaluation results provide a certain theoretical basis for further understanding the background of deep geothermal resources in Puyang City, scientifically formulating geothermal resource development and utilization plans, and promoting efficient development and utilization of geothermal resources.
