| Abstract | A regional hydrological model of the Zhangzhou Basin and its surrounding large catchment is presented. The model includes the Zhangzhou geothermal prospect in the cenm whm fluids with a maximum temperatureof 120'C hav been observed at 0.1 km depth. The model reproduces th observed low temperature gradients in nearby and distant deep wells, and explains the natural heat transfer (> 8.5 MW) of the prospect and the observed high temperatures of the inner reservoir. The Zhangzhou system is driven by terrain-induced forced convection causing deep heat sweeps in the upper must down to at least 5 km depth. The natural fluid flow disturbs the crustal temperature field beneath the whole catchment (>10,000 km2). |
