摘    要:小波分析是一种能在时间(或空间)域和频率域内同时进行局部化信号分析和去噪的方法,它适合于非稳定信号的分析,是一种多分辨率信号处理手段。利用该特点采用Mallat方法对测井曲线进行分解和重构,从而提高常规测井资料的纵向分辨率。

关 键 词:小波变换  Mallat算法  测井曲线  纵向分辨率

Abstract:Wavelet transformation is a new method that can make local signal analysis both in time and frequency domains.It is suitable for the analysis of unsteady singal, and is a multiresolution signal processing technique.Be based on the property,by means of Mallat arithmetic,the method can be used to decompose and reconstruct well log curves,and improve the vertical resolution of the old conventional logs.
Keywords:wavelet transform  algorithm of Mallat  log curves  vertical resolution
