摘要
介绍了小波分析的基本概念和二进小波的分解及重构算法，探讨了测井信号的频谱特征。研究结果表明，利用小波变换技术可以对测井曲线进行频谱分析，并与标准频谱进行对比，确定出加权系数，然后再重构测井曲线，从而达到提高曲线纵向分辨率的目的。在研究区两个区块近３００口井的应用结果表明，该方法可以有效地提高测井曲线的纵向分辨率，为储层的精细评价提供高质量的测井资料。
The basic concept of the wavelet analysis, binary wavelet decomposition and reconstruction algorithm are introduced, and the peculiarities of the frequency of logging signal are discussed. The frequency analyses on log curves are made, and the weighing weighing coefficients are determined by contrast to a standard frequency. Log curves are reconstructed so as to enhance vertical resolution of the log curves. Applications in 300 wells proved that this method is effective. The log curves with high quality for elaborate reservoir evaluation can be provided.
