Research on the occurrence characteristics and formation mechanism of geothermal resources in Zhangjiakou City
[Objective]Zhangjiakou City is rich in geothermal hot springs,but at present,geothermal resources exploration and research work is mainly concentrated in geothermal hot springs outcropping areas,and the rest of the area is basically blank.Analysis and research of deep geothermal features,hydrochemical characteristics,formation mechanism and thermal reservoir structure relationship,re-search and summarize different types of geothermal resources and thermal reservoir structure of geothermal resources in the water-rich features,guide the blank area of geothermal resources exploration,development and utilization of mountainous areas and re-search,and help the'double-carbon'goal to achieve.[Methods]Based on the detailed investigation project of geothermal hot spring resources in Zhangjiakou carried out by Hebei Geology and Mining Bureau,we fully analyze and study the distribution of geother-mal resources in Zhangjiakou,the conditions of thermal reservoirs and reservoir characteristics,conduct research on the mechanism of genesis and analysis of the environment for the formation of geothermal water and analyze the characteristics and advantages of the storage of each geothermal type with examples.[Results]Taking the typical district as a representative,after a large amount of data analysis and research,it is found that there are certain differences in the water volume,water temperature and hydrochemical components of geothermal hot springs(wells)in different geothermal resource types and thermal reservoir structures.[Conclusions]The geothermal resources of Zhangjiakou are divided into three types and seven types of thermal reservoir structure models,provid-ing scientific theoretical support for the exploration and development of geothermal resources in the mountainous areas of Hebei Province.
