| Abstract | The Rehai (Hot Sea) Geothermal field of Tengchong County, Yunnan Province is the largest one in the Chinese mainland. Based on results of geological, geochemical and geophysical reconnaissance surveys since 1973, a conceptual model of the Rehai field can be built. The cap rock of the Rehai field is composed of Miocene stratum about 300m thick and the reservoir rocks are constituted by a seismic low speed layer within the Precambrian Gaoligongshan Group beneath the surface to about 1500m. The heat source of the field be a cooling magma pocket with a thickness of 20 located beneath the surface in the granitic crust. The Rehai field is a hot water system with a reservoir temperature of about 230?C. |
