摘要
天津境内在宝坻断裂以南的广大平原区,蕴藏着丰富的中低温地热资源。随着开采程度的加强,研究地热流体的补给和迳流条件显得日益重要。利用环境同位素技术确定了天津各热层储地热流体的补给来源和年龄。并结合地热流体的水化学特征,初步分析了各热储层之间的联系程度和迳流关系。
Tianjin area is abundant in low to medium temperature geothermal resource on the plain area that lies to the south of Baodi fault. With the strengthen of geothermal exploitation, become more and more important to studying geothermal fluid＇s supply and flow. The paper uses environment isotopic techinique to confirm geothermal fluid＇s origin and age of various geothermal reservoirs. And according to geothermal fluid＇s hydrochemical characteristics to analyze the connected degree and flowing relationship of various reservoirs.
