摘要
基于求解非线性方程组的Ｎｅｗｔｏｎ法［４］，本文提出了电法测井反演的离散牛顿法，并给出了此方法的一些具体改进方案。该方案使此方法不仅保持了收敛速度快的特点，并且收敛范围变大，计算量减小，抗噪声能力也得到增强。通过大量的数值模拟表明，此方法是正确的、可行的。
Based on the Newton method solving a nonlinear equation system, a discreteNewton algorithm for inversion of electric log and its improved measures are proposed herein. The algorithm not only has fast convergence, wide converging range,but reduces the computation time and computational instability. A lot of numericalsimulations show that the algorithm is correct and feasible.
