in conclusion, in a deep fractured rock mass, the communicated fracture network has stronger permeability to form a water-conducting advantageous channel, and a large amount of heat is taken away through convection heat transfer, so that the distribution of a reservoir seepage field and a temperature field has strong non-uniformity and anisotropy;
the change of the reservoir seepage field and the temperature field changes the stress distribution of the reservoir, so that the reservoir displacement field changes; in the initial recharge stage, the displacement of the reservoir is changed greatly under the combined action of water pressure and temperature, after the water pressure in the reservoir is stable, the continuous change of the temperature causes thermal stress, and more matrix rock masses shrink due to cooling along with the expansion of a low-temperature area, so that the displacement field of the reservoir is changed continuously;
