测井曲线的最优分割法自动分层评价

最优分割法是一种常用的自动分层方法。文章针对该方法,设计实现了一套计算机程序应用到具体的B101井测井曲线分层中,但分层结果显示假层位过多和层界面深度点不精确,设想通过综合运用各种界面深度判定方法并建立一个合理的合并薄层规则来改善该方法的实际应用。

Evaluation of Automatic Optimum Division Method with Logging Data

Automatic optimum division method is commonly used to identify layers and the aim of the paper is to evaluate the method. Logging data of Well B101 were used in the paper. The result indicated that the method generated too many false interfaces and did not identify interfaces concisely. Comprehensive analysis from various approaches can give a reasonable result and a reasonable standard of combining thin layers should be established to decrease false interfaces.
