摘要: 基于有序样品聚类分析理论的最优分割法的分层标准客观可靠,但应用中计算量巨大,严重影响其应用推广。在认识了测井资料的层单元特征的基础上,介绍了基于单层均值的最优分割法,即通过对测井资料作单层划分处理,在此基础上再作逐次最优二分割,使计算量大大降低。并通过VB语言编程实现,处理速度快,效果良好。Abstract: The optimum dichotomy based on the theory of or- dered specimen cluster analysis provides an objective and reliable criterion for layering,but because of its excessive calculating in application,the popularization is badly af- fected.By recognizing the single layer section of logging data,an optimum dichotomy based on mean value of sin- gle layer is introduced in this paper.On the basis of single layer division,a successive optimum dichotomy of logging series is realized,which greatly reduces the calculating a- mount.Through VB language programming,the method is popularized and works with a quick speed and favorable effect.
