摘　　要：眉县汤峪地热田位于秦岭山地与汾渭地堑的接触地带,属于典型的断裂裂隙型地热田。笔者基于物探和水文地球化学方面工作对该区进行了系统研究。结果表明:汤峪地热田内主要分布着东西向和近南北向的两组断层构造。这两组构造也成为研究区内主要的导(控)水和导(控)热构造,控制着地热田的分布。地热田内热储层为断层破碎带和裂隙发育地段,具有良好的储水储热性能。地热水由研究区以南的秦岭山区得到补给,补给水源以大气降水为主,补给水径流向地下渗透,经热源加热后成为地热流体。热水在区内断层交汇处上涌,最终形成地热田。Tangyu geothermal field in Mei Country is located in the contact area of Qinling Mountains and Fen- wei graben, belongs to typical fracture type. Based on geophysical prospecting and hydrogeochemical study, we made conclusions： there are two groups of fault structure zones in the geothermal field mainly with east-west di- rection and south-north direction. The two groups of faults have become the most important faults in the study ar- ea. They control not only the water and heat but also the distribution of geothermal field. The heat reservoir of Tangyu geothermal field is faults and fractured zone which can restore a lot of water and heat. The supply area of hot water is in the south of Qinling Mountains. Feed water run down to the underground, then to be the geother- mal fluid after heat source heating. When the hot water encounters faults, it begins to move towards the land sur- face.
