电相分析的自动分层取值方法研究

本文在综合分析比较现有的各种分层取值方法的基础上,对电相自动分层取值方法进行了深入研究,采用极值方差聚类法来实现电相分析的自动分层取值。以辽河油田欧利坨子地区的沙三段复杂岩性剖面为研究对象,处理了欧8井等15口井的测井资料。结果表明,该法简便实用,运算速度快,分层取值合理准确、效果明显。在精细测井相分析中值得借鉴和使用。

Research of Automatic Classifying-Formation Method from Well Logging Curves on Electro-Facies Analysis

Classifying-formation from logging curves is a basic step in the course of automatic electro-facies analysis. This paper studies the method of automatic classifying-formation in a deep going way on the basis of thorough analysis of many normal methods, and uses max-minimum and variance technique to solve this problem. Taking S3formation of complex rocklitho profile in 08 well and other boreholes . The result shows that this method is not only easy, practical, but also fast in calculation and reasonable and accurate in classifying formation. Therefore it can be adopted for reference and applied in fine log facies analysis.
