| Abstract: | Geothermal resources are widely distributed in China. In recent years, a lot of research work has been carried out on the distribution, utilization, drilling, and exploration of geothermal resources. However, there is almost no record of geothermal reinjection in China. Based on geological characteristics, geophysical and geochemical features of Xi'an low-temperature geothermal field,this paper has established for the first time a 3-D numerical model to simulate the change of temperature and pressure after reinjection. The results show that making reinjection at the depth of 1 450 m to 2 300 m will benefit the reservoir pressure with no remarkable change in temperature. |
