High-density Resistivity Technique Topographic Correction Research

High-density resistivity method from the principle point of view, belong to resistivity method. topographic correction status and progress of the study.Secondly, the use of two-dimensional finite element method.Preparation of procedures valley, ridge topography of vertical and horizontal high and low resistance anomaly numerical simulation of two-dimensional geological model.In accordance with high-density electrical prospecting in the wener quadrupole device, Pointsat different depths were calculated apparent resistivity.The final analysis of the topography of the DC resistivity method of exploration should not affect,and the use of conformal mapping of the Schwartz-Christoffel mapping method of the above forward modeling study of the data terrain correction.Conclusions of this paper, through theoretical models and field data processing engineering practice,Conformal mapping of the geological conditions, fluctuation of high-density electric exploration of the terrain correction has a effective results...
