基于常规测井曲线频谱分析的多尺度地质分层

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

测井曲线的频谱具有其特殊的地质意义,即测井曲线的不同频率与不同尺度地层相对应。首先讨论了测井曲线频率与地层的关系,进一步给出了用带通滤波进行多尺度地质分层的方法,最后,通过一个实际分层实例,说明了方法的正确性和有效性。

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.
