Design and Key Points Analysis of the Intermediate-depth Geothermal Central Heating Project in Pingyuan County

Abstract

In the past 20 years, In China deep geothermal heating projects have developed rapidly, in the scale of the world top. It is understood that Iceland can provide central heating for 90% of homes by developing medium-and deep-seated geothermal reservoirs. Germany has gradually made medium-and deep-seated geothermal reservoirs a key target for development, to meet the heating needs of Germany 1/4. Based on the actual engineering project, this paper analyzes the geothermal state, key technology, core parameters and so on in the project engineering design, and compares and selects the schemes in the design, finally, the optimal design scheme is determined and the economic benefit is analyzed. The key problems in engineering design are summarized and some suggestions are put forward.
