起伏地形条件下FPS不同解释方法对比
Different interpretation methods of FPS in undulating topography conditions
摘要
Abstract
The fixed point source IP sounding (FPS)is a kind of effective excitation polarization sounding exploration method. But in the data interpretation,regular quantitative interpretation of arc intersection - relative intensity (AIRI)method just a-dapt to some simple geoelectric conditions and models,affected by the undulating topography conditions obvious.Aiming at the deficiencies and defects of regular quantitative interpretation methods,this study calculates a plurality of geoelectric model in-stance based on the forward modeling of the finite element method,used the least square method,and wrote the program with VC++.Then the AIRI calculation results and the least square inversion results were compared.The results showed that the least square inversion method can adapt to various geoelectric conditions to inversion,the inversion effects is superior to the cal-culation results of the AIRI method.关键词
