摘要
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.
