| 摘 要： | 电阻率三维反演参数太多,将导致反演不稳定性和高度非唯一性等诸多方面的问题。比较传统的最小二乘反演方法,利用共轭梯度的电阻率三维最小构造反演显示了更好的效果。讨论了初始模型选择及数据误差对三维反演结果的影响,说明了反演方法的稳定性和可靠性。

| Abstract: | Many inverse parameters result in problems such as non-uniqueness and unstability in 3-D resistivity inversion .The 3-D resistivity inversion for minimum stricture using conjugate gradients shows good results as compared with traditional inversion method of least squares. We also studies how the initial model and data errors influence the results of 3-D inversion in this paper, in order to investigate stability and reliability of the 3-D inversion method. |

| Keywords: | D resistivity inversion conjugate gradient stability reliability |
