| 摘 要： | 本文将油田电阻率测井求地层电阻率分布的物理模型归结为一个带有衔接条件的椭圆型偏微分方程反问题,并用迭代过程求解出地层电阻率,从而给出了一种摆脱图版的测井解释方法。本文最后给出了方法的收敛性证明。

| Abstract: | In this paper, the physical model of the electrical log in geophysical prospecting is reduced to the inverse problem of an elliptic partial differential equation and an iterative algorithm is used to solve this inverse problem so that formation resistivities can be identified. Many examples of the case of laterolog 3 are computed and numerical simulations are carded out to test the feasibility. It is shown that this numerical algorithm is effective and robust. Finally, the convergency of the method is proven. |
