Abstract
In order to get the change of surrounding rock temperature during hot dry rock reservoir productive process, we used the Transport of Unsaturated Groundwater and Heat (TOUGH2) software to simulate the model which attached surrounding rock to hot dry rock (HDR) reservoir. On the condition that we set actual production and reservoir parameters to the model, we calculated change of reservoir temperature and surrounding rock while the HDR reservoir exploitation within 20 years. The result shows that the temperature of surrounding rock which is more than 100m away from injection well almost will not be changed.
