Abstract: A new distorted Born iterative method is applied to inversion of large formation region by using the multi information of array.The region consists of the complicated transition zones and the raw formation without mud invasion.The method,based on nonlinear integral equation,is used to solve for the formation conductivity profile by using regularization.In each iteration,the numerical mode matching method is used to solve the forward problem of the induction.Some simulations show that the imaging results are in much good agreement with the true conductivity profile by array multi-information on the axis of symmetry.
