摘要:This paper analyzed genetic models of the geothermal water with middle low temperature in Huangshadong geothermal field which is one of the most important hydrothermal regions in the southeast coast of China. The flow pattern of geothermal water is replenished by precipitation, heated by circulation, and finally rises to the surface through cracks. The hydrochemical types of geothermal water in the study area is Na-HCO3, and the hydrochemical types of non-geothermal water in the study area is Ca-HCO3. The content of HSiO2, Li, Sr, Ba and F were significantly enriched in geothermal water. Geothermal water in Huangshadong has larger circulation depth, longer flow time and smaller circulation rate, which make it obtain more heat than other geothermal water in the surrounding areas. According to the comprehensive analysis of the thermal field in the study area, there have two reservoirs for Huangshadong geothermal field, the shallow reservoir temperature is about 125°C, the deep reservoir temperature is about 180°C.
