The results show that the leading fracture channels between wells of the fractured heat reservoir in Xian region geothermal field play a crucial duty in regulating the seepage warm transfer. Under the coupling activity of the seepage field, pressure field and the temperature level field of the warm reservoir, the low-temperature tail water reinjection creates a preferential flow along the dominant networks, which is just one of the essential variables to take into consideration in the prediction of thermal advancement. In the pumping and reinjection system of Xian area geothermal area, under the problems of 0. 5 MPa reinjection pressure, 30 ° C reinjection tail water temperature and 270 m spacing in between pumping and reinjection wells, the warmth reservoir temperature level at the pumping side decreased by 1. 5 ° C in 100 years.
