江苏东海温泉热储温度估算

Estimation of geothermal reservoir temperature for the Donghai hot spring in Jiangsu

以东海温泉为例,依据8个热水样品的水化学分析数据,讨论了区域地质背景下热储温度的估算。分析认为：东海温泉为同源的地热水,热水在上升过程中发生冷水混合作用;对比不同地热温标的适用条件,分别采用Na-K-Mg三角图法、硅温标混合模型方法计算热储温度。结果显示：2种方法的计算结果较为接近,东海温泉的热储温度在153~170℃之间。

This study estimated the geothermal reservoir temperature of the Donghai hot spring in Jiangsu Province based on water chemical analysis of 8 water samples. The result shows that,the Donghai hot spring contains homologous geothermal water,which underwent cold water mixing during the rising process. The triangular Na-K-Mg method and the mixed model of silicon geothermometer are used to calculate the geothermal reservoir temperature on the basis of the different applicable conditions for geothermometers. It is suggested that,the geothermal reservoir temperature of the Donghai hot spring calculated by the two methods varies little,and ranges from153 to 170 ℃.
