| Abstract: | In this paper, the inversion and reconstruction of induction tool measurements with the distorted Born iterative method (DBIM) and an efficient Numerical mode-matching (NMM) method is described. The nonlinear problem is linearized at each step by using distorted Born approximation.Therefore, the electromagnetic (EM ) intergral equation can be performed by using the Tikhonov regularization method and iteration method. In each iteration of DBIM, a numerical mode-matching method is applied to solve the logging response data and the Green's function in the complex media. In this paper the analytic expression of the integration in the nonlinear integral epuation has been derived and then the inversion of the efficiency and accuracy improved dramatically. The method is practical for the interpretation of electrical logging data. |
