  • High temperature geothermal system contains plenty of geothermal resources. In order to further understand the high temperature geothermal system, taking the Rehai geothermal field of Tengchong as a typical study area and the geochemical compositions of Rehai hot springs as basic data, the temperature of parent geothermal fluid (PGF) below Rehai is estimated by use of multiple geochemical models, based on which the cooling processes of PGF during its ascent to surface are analyzed as well. The geothermal waters discharged from both Liuhuangtang and Reshuitang of Rehai originate from the same deep reservoir where a parent geothermal fluid with Cl- concentration of 265 mg/L and temperature of 336 ℃ was identified. The Dagunguo spring with the highest vent temperature at Rehai was formed via direct adiabatic cooling of PGF, whereas the other neutral springs are primarily the results of mixing between PGF and shallow cold groundwater, although boiling was also involved after the mixing. Above the deep reservoir containing PGF, there exist many geothermal reservoirs with temperatures higher than 200 ℃. The formation of these reservoirs is possibly controlled by the faults with different stretching directions at Rehai.
