Abstract: The 3D resistivity inversion using the conjugate gradient(CG) method has been developed in recent years and has many problems that remain to be studied.This paper studies how the Lagrange factor λ and CG iterative times influence the results of 3D inversion.The main purpose is to yield good results of 3D inversion.

Key words: Resistivity, 3D inversion, Conjugate gradient, Lagrange factor
