摘要
本文提出的方法是以电极电位和电流作为记录数据,将地层电阻率分布视为未知待求函数,对问题所构成的微分方程反问题进行迭代求解,从而可以不借助于解释图版获得地层电阻率。
<ABSTRACT> In this paper, the physical model of the eletrical log in geoph ysical prospecting is reduced to the inverse problem of an ellipse equation and iterative algorithm is used io solve this inverse problem so that formation re sistivities can be identified.Many examples of the case of laterolog 3 are com puted and numerical simulation are carried out to test the feasibilty.It is shown that this numerical algorithm is effective.Finally, the convergency of the method is proved.
