A Multi-Criterion Geological Stratification Method Based on Conventional Log Curve Spectrum Analysis

YI Jue-fei (Yangtze University,Jingzhou 434023)  
Log curve frequency spectrum had its special geological significance,namely,log curve of different frequencies was corresponded with different criterion stratum.In this paper,we discuss the relationship between log curve frequency and the stratum,and propose a method to analyze the multi-criterion geology lamination with the band-pass filter.The example analysis explains the accuracy and the validity of the method.
