Abstract:Yuncheng area is rich in geothermal resources, which are mainly stored in the Ordovician and Cambrian systems. In order to estimate and evaluate geothermal resources in this area, one geothermal well has been constructed. In combination with the collected data of more than 30 geothermal wells in this area, geothermal occurrence conditions in Yuncheng area have been basically found out, and the Ordovician and Cambrian thermal reservoirs have been determined as the object of this study. The quality of geothermal fluid in Yuncheng area has been evaluated, and the amount of geothermal resources has been calculated. The evaluation provides data support for sustainable development and utilization of geothermal resources in Yuncheng, driving local economic development and building an energy conservation society.
