| 摘 要： | 热储温度是划分地热系统成因类型和评价地热资源潜力的重要参数。文章在采集分析渝东南13个地热水样的基础上，利用无蒸汽损失石英和有蒸汽损失石英温标法、玉髓法a和玉髓法b，修正的SiO2温标法，K-Mg、Na-Li、Na-K、Na-K-Ca等阳离子温标法计算渝东南深部热储温度，并利用Na-K-Mg三角图解法和矿物饱和指数法检验所用方法的可靠性，结果表明:研究区利用SiO2(无蒸汽损失)温标法和修正后的SiO2温标法计算所得出的热储平均温度更适用，各地热水点热储温度范围在62.78~124.81℃，平均热储温度88.98℃。

| Abstract: | Geothermal temperature is an important parameter for identifying genetic types and thermal sources. On the basis of analysing 13 geothermal water samples collected in Southeast Chongqing, this paper used various methods to calculate the deep thermal storage temperature in Southeast Chongqing, including the methods of steam-free loss quartz and steam loss quartz temperature scales, chalcedony a and b, modified SiO2 temperature scale, K-Mg, Na-Li, Na-K, Na-K-Ca and other cationic temperature scales. Meanwhile, and as well as the Na-K-Mg triangulation method and the mineral saturation index method were also employed to test the reliability of these methods. The results show that the average temperature of thermal storage calculated by SiO2 (no steam loss) temperature scale and modified SiO2 temperature scale is more applicable. The thermal storage temperature range of hot water points at various places is 62.78~124.81℃, and the average thermal storage temperature is 88.98℃. |
