摘　　要：通过分析豫西栾川潭头盆地断裂系统、热储成因类型、热储类型、地热流体流场特征及动态、地温场特征以及地球化学特征,研究了豫西栾川潭头盆地地热地质特征。研究得出,研究区内主要断裂为马超营断裂,为主要控热断裂;热储为断裂破碎带,呈带状展布;研究区恒温带埋深为30m,平均地温梯度为3.70℃/hm;研究得到了地热流体化学组分特征、动态变化以及同位素化学与地热田成因。研究为地热水资源的开发利用提供了理论基础。The geothermal geological characteristics of Luanchuan Tantou Basin in western Henan,which were studied by analyzing the fault system,the type of thermal reservoir,the type of heat storage,the characteristics of geothermal fluid flow field,the characteristics of geothermal field and the geochemical characteristics of the Tantou Basin in Luanchuan,western Henan.The study showed that:the main fault in the study area was the Machaoying fault,which was the main heat-controlled fault;the thermal reservoir was a fracture-fracture zone with a strip-like distribution;the constant temperature zone of the study area was 30 m,and the average geothermal gradient was 3.70℃/hm;research had obtained the characteristics,dynamic changes of geothermal fluid chemical components and the genesis of isotope chemistry and geothermal field.The research provides a theoretical basis for the development and utilization of geothermal water resources.
