高密度电法在山区浅表层结构调查中的应用

THE APPLICATION OF THE HIGH DENSITY RESISTIVITY METHOD TO THE INVESTIGATIONOF SHALLOW LAYER STRUCTURE IN THE MOUNTAIN AREA

南方山区浅表层地质条件复杂,进行高密度电法测量,以微测井和浅表地质调查成果作为依据,对高密度电法资料进行综合解释,查明表层结构和低降速带的分布特征,为取得高品质地震资料品质处理提供依据。

The method discussed in this paper can replace part of the drilling work.Shallow geological conditions of the mountain areas in southern China are complex.In order to obtain high-quality seismic data,the authors have adopted the high density resistivity method.This method takes micrologging and shallow geological survey as the basis for comprehensive interpretation of high-density resistivity data so as to identify the distribution features of surface structures and low velocity layers,guide the well depth design and provide evidence for obtaining qualified seismic data processing.
