云南省腾冲县热海地热田是中国大陆上最大的一个地热田。根据１９７３年以来所获得的地质、地球化学和地球物理资料，有可能建立热海地热田的概念模型。热海地热田的盖岩层为厚约３００ｍ的中新统；热储岩层为前寒武系高黎贡山群内的低速层，埋深约１５００ｍ，热储流体为ＮａＣｌ型饱和水，温度为２３０～２７５℃；热田的热源为地下６～７ｋｍ深的一个岩浆囊，它侵位于花岗岩之中，厚约２０ｋｍ，其顶部的温度约为６６７℃。
Thermal Haiti, Tengchong County, Yunnan Province is the largest geothermal field in mainland China. Based on the geologic, geochemical and geophysical data obtained since 1973, it is possible to establish a conceptual model of the thermal Haiti thermal field. The thermal stratum is a low-velocity layer of the Precambrian-Gaoligongshan Group with a depth of about 1500 m. The thermal storage fluid is NaCl-type saturated water and the temperature is 230 ~ 275 ℃. The heat source of the thermal field is a magma chamber 6 ~ 7km underground, which intrudes into the granite about 20km thick and its top temperature is about 667 ℃.
