摘要
小波分析是近年来发展起来的一门新的数学分支,且开始广泛应用于众多科技领域。本文叙述了小波分析在未来测井技术中的几个重要应用。例如,在编码数据压缩中,可以大大压缩巨大的测井数据量;用多分辨率分析对信号进行高信噪比分离和滤波;新的抽样定理适用于Sh取样定理不能适用的非频谱有限情况;对测井曲线进行小波分析分形讨论能得到更为细致的局部性质,因而更有益于测井解释。
Xia Kawen.Wavelet Analysis in Well Logging Technology.WLT,1993;17(4):252～255 Wavelet analysis developed in recent years is a new mathematic branch and is being widely used in many scientific fields.Several applications of wavelet analysis in future logging technique are briefed in this paper: ①Large quantity of logging data can be compressed greatly by encoded data compression;②Signal can be seperated and filtered with high signal-noise ratio by multi-resolution analysis;③New sampling theorem is especially effective to the finite condition of non-frequency spectrum,which Shannon theorem is not;④ Much more detailed local properties can be studied through fractal discussion of logs of wavelet analysis, which will be helpful to log interpretation.
