| 中文摘要: |
| 贵州苗匡热矿水地热区大地构造位于江南复合造山黔南坳陷铜仁复式褶皱变形带，区域构造为红石古断裂带与苗匡断裂交汇锐角区，区内出露的地层有前南华系板溪群、南华系、震旦系、寒武系；热矿水水化学类型为HCO3-Na型，含高氟、锶、锂、偏硅酸；弱碱性水；呈带状中低温热储；区域大地流热供给热量；地下热矿水补给为构造破碎带深远程补给；区域性红石活动断裂带具有导热导水储水性，热矿水被温差、压力差等驱动循环运移至断裂破碎带富集，苗匡次级断裂带在该热储起到联通传导作用；热矿水井口温度45℃，出水量560m3/d。研究结果可对该区热矿水勘查开发及利用提供参考和借鉴。 |

| The geotectonic element of MiaoKuang geothermal anomalous area is located in the TongRen complex fold deformation zone, QianNan?sag,JiangNan complex orogenic belt.In regional structure, it belongs to the intersection acute Angle area of HongShi palaeo-fault zone and MiaoKuang fault.In the research area,the exposed strata include pre-nanhua system banxi?group、nanhua System、sinian system、cambrian system；The type of hot mineral water is Hco3-Na,which contains fluorine, strontium, lithium, metasilicate acid,and is weakly alkaline water,belongs to medium-low temperature stratified reservoir.Regional heat flow supplies heat,and regional HongShi active fracture zone have thermal conductivity,transmissivity,water storage.The hot mineral water is driven by temperature difference and pressure difference to migrate circularly to the fracture zone for enrichment,the secondary fault zone in miao-kuang plays a role in the conduction of the heat reservoir.The wellhead temperature was 45℃ and the water output was 560m3 /d.The study results can be used as reference for geological survey and utilization of geothermal?mineral?water in this area. |
