Evolution of Periodic Thermal Recovery Performance of Hydrothermal Geothermal Multiple Wells
Hydrothermal geothermal resources are a renewable energy source that can be developed for building heating and can effectively save energy and reduce emissions.The thermal performance of hydrothermal geothermal wells was investigated based on real-time fiber optic transmission technology and actual on-site operating parameters combined with numerical simulation methods.The results indicate that the fluctuation of outlet temperature during the heating period is relatively stable throughout the production process,and the minimum temperature can reach 70.7 oC.During the entire mining cycle,the maximum horizontal disturbance range of the temperature field within the reservoir is 188.2 m,indicating that the geothermal reservoir has good sustainable mining characteristics.During the 30-year mining cycle,the groundwater level has dropped by a maximum of 2.56 m,with minimal impact on the local groundwater environment.The building heating area of the geothermal extraction system in the research area is between 1.82×104-4.86×104 m2,and there is no significant attenuation during the continuous heating cycle.
