| 本文以研究中国东部渤海湾盆地沧县隆起北部天津地区雾迷山组地热流体的化学特征和径流模式为目的，系统分析了研究区63眼雾迷山组地热流体水化学数据，运用统计分析和综合研究方法，分析了研究区不同构造单元雾迷山组地热流体的水化学类型、主要离子组分含量、离子来源、离子变化规律等，探讨了研究区雾迷山组地热流体的径流方向和特征分析，认为地热流体主要来源于北部山区的大气降水，入渗后向南、向东径流，径流过程中 Na+和Cl-含量逐渐升高，溶解性总固体（TDS）逐渐增大，水-岩反应过程随径流过程持续发生，但水-岩反应平衡度仍然偏低，未达到平衡状态。汉沽断裂、海河断裂、白塘口西断裂与白塘口东断裂均为导水断裂，而白塘口凹陷的存在也并未改变雾迷山组地热流体的径流方向。 |
| 英文摘要: |
| Aiming to study the chemical characteristics and runoff pattern of geothermal fluid in the Wumishan reservoir in the Cangxian Uplift area of the Bohai Bay Basin in eastern China, this paper systematically analyzed the hydrochemical data of geothermal fluids from 63 geothermal wells in the Wumishan reservoir within the study area. By adopting statistical analysis and comprehensive research methods, the paper obtained information on hydrochemical types, major ion concentrations, ion sources, and ion variation laws of the geothermal fluid in the Wumishan reservoir across different tectonic units in the study area. Additionally, it discussed the runoff direction and characteristics of the geothermal fluid in the Wumishan reservoir. The study concludes that the geothermal fluid originates from atmospheric precipitation in the northern mountainous areas; after infiltration, it runs off southward and eastward. During the runoff process, the contents of Na+ and Cl- increase gradually, and the Total Dissolved Solids (TDS) also increase progressively. The water-rock reaction process occurs continuously along side the runoff process, yet the degree of water-rock reaction equilibrium remains low, far from a balanced state. All boundary faults of the tectonic units are water-conducting faults, and the existence of these water-conducting faults and depression areas does not alter the runoff direction of the geothermal fluid in the Wumishan reservoir. |
