Inversion of the Cole-Cole Parameters from Spectral Induced-polarization Data Using L-curve Method

摘要：

　　A special scheme of nonlinear regularized least-squares inversion was develop to decompose combined Cole-Cole model.To distinguish the induced polarization and EM coupling effects,a recursive method like Ruan (2003) was developed to create initial model and priori model.In the scheme,staggered the magnitude and phase as inversion data,the L-curve method was used to establish regularize stabilizer.This inversion method has high precision characteristics of the deterministic method and ensure that the solution of the reasonableness.
