Short summary
In this study, a coupled thermo-hydro-mechanical (THM) model is implemented to simulate the processes of heat extraction, reservoir deformation, and groundwater flow in the fractured rock reservoir. The results show that the growth of the number and spacing of fracture zones can effectively decrease the pore pressure difference between injection and abstraction wells; it also increases the production temperature at the abstraction, the service life-spans, and total heat production rate.
