MODFLOW Application on the Numerical Simulation of Geothermal Fluid in Tianjin Binhai New Area

ZHANG Fen-na;JIA Zhi;GAO Liang;LIU Jiu-long;Tianjin geothermal exploration and designing institute;China University of Geosciences;  
In order to rational development and utilization of geothermal resources in Tianjin Binhai NewArea,we take Minghuazhen geothermal fluid in the Qiaogu-Kancaizhuang Neogene Minghuazhen Formation as an example, do numerical simulation with Visual MODFLOW software. The result Indicate that the calculation model can reflect the dynamic characteristics of groundwater level in the geothermal fluid. It is suggested that in100 years, geothermal fluid geothermal fluid level close to 150 m recoverable reserves is about 10.7×106 m3/a.Accoding to the prediction of changes in the design of mining Minghuazhen geothermal fluid of underground water level, to add 1000 m3 exploitation of dayis feasible.
