LOW-TO MID-TEMPERATURE THERMAL STORAGE AND THERMAL FIELD IN HOLES

The groundwater with low to mid temperature has great potential for development and usage.The research on its origin and occurrence is the foundation for rational exploitation and development.In the light of stratigraphic and hydrogeologic conditions,the development conditions conductive thermal storage are studied as well as the primary types of thermal storage are divided,based on the principles of geothermal conducrion.The variation regularities of thermal field and the temperature of drilling fluid are analyzed,providing the temperature distribution curves of drilling fluid and corresponding correlation between temperature and strata.The result is available for guiding the thermal groundwater development.
