The global energy structure is undergoing a fundamental shift from a reliance on fossil fuels with clean energy as a supplement

to a focus on clean energy supported by fossil fuels. Clean

renewable geothermal resources are gradually becoming a key energy source for sustainable development. This study focused on Gaocheng District in southwestern Hebei Province

leveraging its unique geological structural characteristics and abundant geothermal reserves. A refined geothermal resource assessment system was established

forming the basis for optimal well placement and spacing for efficient geothermal resource development. Results indicated that the development area had excellent heat source conditions

a highly favorable reservoir-caprock system

and low scaling and corrosion risks from formation fluids

indicating high-quality geothermal resources. Forty extraction and reinjection wells were deployed with a 1:1 ratio（20 extraction wells and 20 reinjection wells）. With a well spacing of 380 m and a projected operational lifespan of 30 years

the setup was expected to support sustainable heat exchange and heating needs. Based on geological structural characteristics

this study provides a valuable reference for the sustained and efficient exploitation of geothermal resources.
