    Analysis of geothermal temperature and genetic model in Zhaojue County of Sichuan Province

    • 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。为合理开发和利用四川昭觉县的地热资源,巩固脱贫攻坚成果,选择四川昭觉县竹核温泉为研究对象,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,其中竹核温泉中大温泉的热储温度范围在81~93℃之间,平均热储温度86℃,小温泉的热储温度范围在77~90℃之间,平均热储温度82℃;竹核温泉来自深部的大地热流,受控于木佛山断层和竹核断层2条主控断裂。

       

      Abstract: Geothermal temperature is an important parameter for classifying the genetic types of geothermal systems and evaluating the geothermal resource potential.In order to rationally develop and utilize the geothermal resources in Zhaojue County of Sichuan Province, and consolidate the achievements of poverty alleviation, the geothermal temperature of the Zhuhe hot springs in this area was studied.Various methods were used to calculate its deep thermal storage temperature, including 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.The reliability of the above methods is tested by Na-K-Mg triangulation method and mineral saturation index method.The results show that the average temperature calculated by SiO2 (without steam loss) temperature scale method and modified SiO2 temperature scale method are most suitable for this hot springs.The thermal temperature of its large hot springs ranges from 81℃ to 93℃, averaging 86℃, and that of small hot springs from 77℃ to 90℃, averaging 82℃.It reveals that the Zhuhe hot springs results from the deep terrestrial heat flow and is controlled by Mufoshan fault and Zhuhe fault.
