摘　　要：高密度电法具有点距小,采集数据量大,采集效率高,探测精度高和探测深度大等优点,在工程地质和水文地质勘查中广泛应用。该次物探工作将高密度电法应用于某工区的地热勘察中,验证了高密度电法在地热勘探中的可行性。采用温纳装置采集的视电阻率数据,经过软件反演后的视电阻率异常特征和断面清晰地反映出裂隙地下延展分布、地下埋深情况,取得了很好的地质效果,为地热勘探提供了地球物理依据。The high density resistivity method has the advantages of small space between points,large density in data collection,high efficiency,high observation precision and big observation depth etc.,and it is used in engineering geology and hydrogeology exploration widely.In this paper high density resistivity method was used in geothermal exploration in certain work area,and the results proved high density resistivity method is feasible in geothermal exploration.The apparent resistivity data collection by using Wenner device,apparent resistivity anomaly characteristics and section by software inversion can clearly inflect the fracture spreading distribution and underground buried depth.It gets good geological effect,and provides the geophysical basis for geothermal exploration.
