中文摘要:
      本文利用水文地球化学和环境同位素调查方法,对天津市中心城区附近各主要热储层间的水力联系进行了探讨。研究结果表明,大气降水是天津市中心城区附近各热储层的补给水源,各热储层之间存在不同程度的水力联系。环境同位素水文地球化学证实,各大断裂是沟通天津市中心城区附近各热储层间水力联系的关键因素。
英文摘要:
      Hydrogeochemistry and isotopic investigation methods are used in evaluating hydraulic connection between geothermal fluid in different geothermal reservoirs. The results show that all geothermal reservoirs in the central districts of Tianjin is recharged from precipitation, and the hydraulic connecting among geothermal fluid in different reservoirs. The environmental isotope and chemistry compositions data of geothermal water samples provide further evidence that the major faults is a key factor of hydraulic contacting in different geothermal reservoir in the central districts of Tianjin.
