摘　　要：近年来,地热资源深部探测的需求越来越大,尤其是在强干扰地区如何能够压制噪声、采集到有用信号成为电磁法勘探成功的关键。广域电磁法具有抗干扰能力强、探测深度大等优势,本文在渭河盆地北部礼泉县一带布设了1条广域电磁剖面,基本查明了剖面范围内的深部电性特征,厘定了地层分布和山前断裂带信息,为该地区地热资源开发利用提供了依据。In recent years,the demand for deep exploration of geothermal resources has been increasing,especially in the strong interference area,how to suppress noise and collect useful signals has become the key to the success of electromagnetic exploration.The wide field electromagnetic method has the advantages of strong anti-interference ability and large detection depth.In this paper,a wide field electromagnetic profile was deployed in the northern part of Weihe Basin around Liquan County,which basically identified the deep electrical characteristics within the profile range,and determined the stratigraphic distribution and information of the piedmont fault zone,providing a basis for the development and utilization of geothermal resources in this area.
