| Abstract | The development of mid-deep geothermal resources has great potential, but there is still much room for improvement in the efficient and sustainable utilization of geothermal energy. In order to ensure the efficient utilization and sustainable development of geothermal resources, this paper takes a mid-deep geothermal heating project in a certain area of Henan Province as an example. The project system adopts the cascade utilization of geothermal heat. Compared with municipal heating, it has decreased by 4.42 yuan/square meter, and at the same time saved 45,500 yuan of environmental treatment costs. The mid-deep geothermal heating project using cascade utilization expands the heating capacity of the system, improves the utilization efficiency of geothermal water, and provides a basis for the full utilization and rational development of geothermal resources. |
