Abstract

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

摘要： 利用共轭梯度方法的电阻率三维反演是近几年才发展起来的,尚有诸多问题有待探讨。主要讨论了拉格朗日因子λ、共轭梯度迭代次数对三维反演结果的影响,以便获得良好的三维反演效果。

关键词: 电阻率, 三维反演, 共轭梯度, 拉格朗日因子
