| Abstract: | Geothermal water in the basement aquifers near Tianjin is characterized by a significant change in density of the water with its temperature and an exchange of heat between the water and its surrounding rocks. This paper puts forward the governing equations of pressure and temperature for describing water flow and heat transport of the deep seated geothermal system. The 3 dimensional numerical model established are proved more effective and practical by the reasonable generalization and treatment of the flow domain, boundary and initial conditions, missing areas of the aquifers, and tilted faults. |

| Keywords: | geothermal water 3 dimensional model numerical modeling density pressure temperature. |
