Evaluation of development potential and application prospect of geothermal resources: A case study of Xiangfu District in Kaifeng
geothermal resources as a renewable energy source have attracted widespread attention. This study evaluated the geothermal resource development potential and application prospects in the Xiangfu District of Kaifeng City. The results showed that the vertical temperature field of the thermal reservoir in the Xiangfu District could be divided into varying temperature zones
constant temperature zones
and increasing temperature zones
with depth significantly influencing the temperature distribution. The geothermal gradient increased with depth above 500 m and gradually decreased below 500 m. Chemical analysis of geothermal fluids show
ed significant differences in the water chemistry types between thermal reservoirs at different depths
with no significant hydraulic connection between the reservoirs. Based on the maximum allowable depth reduction method and the extracted water volume method
the total exploitable geothermal fluid without reinjection was estimated to be 9

. Under complete reinjection conditions
the total exploitable geothermal fluid was estimated to be 360.7×10

indicating substantial development potential. These research findings provide a scientific basis and guidance for the efficient development and utilization of geothermal resources in the Xiangfu District.
