摘要
以天津地区大量的地热流体水化学数据为研究对象,利用Q-型聚类分析法,以构造单元及热储层为分类依据,将研究区分为17个亚类进行逐级聚类。结果表明:地热流体的水化学特征与地质构造单元、热储层特征有着较好的相关关系,与传统地球化学研究方法的结论一致。而且该方法具有客观、高效、直观的特点,所以对水质数据积累较多的地区,利用聚类分析法研究地下水的地球化学特征具有很好的应用前景。
A large number of hydrochemical data of geothermal fluid in the Tianjin area are examined in this paper.The Q-type cluster analysis method is used based on tectonic units and geothermal reservoirs.According to tectonic units and geothermal reservoir,the study area is divided into 17 subtypes and clusted step by step.The results show that the hydrochemical characteristics of the geothermal fluid in the study area are related to the geological tectonic units and are in good agreement with the characteristics of heat reservoir,which are consistent with the traditional conclusions of hydrochemistry.The results are reliable,intuitive and efficient.The methods has a good application prospect in groundwater quality analyses.
