摘要
测井解释中岩性成份的分析是一个多参数的非线性反演问题,最优化变尺度法比较适合求解这一类问题,而且收敛速度快、效果好。这里主要讨论如何利用最优化变尺度法进行测井资料的岩性解释。首先介绍了最优化变尺度法的原理及其实现步骤,然后论述了最优化变尺度法在测井解释中的应用,包括目标函数的构制、岩性成份分析模型的建立,最后给出了最优化变尺度法在某井段岩性解释中的应用效果。
In logging interpretation, the analysis of rock composition is a multi-parameter and nonlinear problem. This paper mainly discusses the interpretation of the lithology with logging data by optimization variable scale method. At first, the paper introduces the theory and realizing steps of the optimization variable scale algorithm and then expatiate the application of the optimization variable scale method in logging interpretation, involving in the building of object function and the construction of formation model. Finally, the paper shows the application results of the optimization variable scale method in the lithology interpretation with one well data.
