摘　　要：高密度电阻率法以其他电法勘探方法所不具备的快速高效、操作简单、装置选择多样、采集信息丰富、成本低廉的优势,来应对现在普通物探方法已难以满足的、越来越复杂的地质调查任务。在新疆某地区高地使用DUK-2A高密度测量系统实验,运用高密度电法中的温纳、偶极、微分3种排列装置完成对数据的采集,运用Geogiga RTomo软件对原始数据进行处理和反演,得到反演电阻率剖面图,然后对勘探效果进行对比,探讨温纳、偶极、微分3种排列装置对高阻体和低阻体识别效果的差异,为高密度电法在勘探工作中选用何种排列提供参考。High density resistivity method has the advantages of high efficiency, simple operation, diverse device selection, rich information collection and low cost, so it can cope with the increasingly complex geological survey tasks. In this paper, DUK-2 A high-density measurement system experiment was used in an area of Xinjiang. The Wenner, dipole and differential array devices were used to complete the data acquisition. The original data were processed and inversed by using the software of Geogiga RTomo, and the inversion resistivity profile was obtained. Then the exploration effect was compared and discussed. The difference in the recognition effect of the three arrangement devices of Wenner, dipole, and differential on high-resistance and low-resistance bodies was discussed, which could provide reference for choosing suitable arrangement way in the exploration work of high-density electrical method.
