With the advantages of green, clean and easy exploitation, geothermal energy is widely distributed and has irreplaceable role in the fields of heating, tourism, spa bath, health care and cultivation & breeding. Guide area is located in the “Source of Three Rivers” area, the development and utilization of geothermal resources will play a role in ecological environment protection there. Heat exchange process was used in DR1 deep geothermal well in Guide basin, the water outlet temperature increased from 41℃ to 46℃, the outlet temperature of geothermal well was risen by self heat exchange of high-temperature rocks at the bottom, which can be reference for geothermic warming in similar strata.
