摘要:
 测井曲线是一种在不同测井方法、不同地质环境、不同地层条件下测得的包含地球物理化学等信息的数据的表现形式。针对测井曲线信号中存在的噪声以及其形态特征的性质，结合分析了双线性插值算法及测井曲线小波变换原理，提出一种改进的小波双线性插值算法在测井曲线相似性判断中的应用。改进的小波双线性插值法在有效滤除测井信号中的噪声的同时，又可以保留曲线的细节信息，对进行测井曲线相似性对比中提供了良好的预处理基础。利用斜率距离度量方法判别分析对经改进的小波双线性插值后得到的测井曲线的详细的特征信息进行判断，进行测井曲线相似性识别。实验结果表明，该方法在进行测井曲线相似性对比中得到了很好的应用。
Abstract:
 Well logging curve is a means of data expression to be measured in different logging methods,different geological environ-ment,different geological conditions including geophysical and geochemical information. According to the nature of the morphological features and the existence of the noise of logging curve,combined with the analysis of the bilinear interpolation algorithm and the wavelet transform principle of logging curve,propose a kind of improved wavelet bilinear interpolation algorithm to apply the similarity of judg-ment in well logging curves. The improved wavelet bilinear interpolation can filter noise effectively in logging signal,at the same time can keep the detail information of the curve,which provide a good basis for the pre treatment for the logging curve similarity comparison. The measure methods of discriminant analysis information with features of logging curve by the improved wavelet bilinear interpolation is ob-tained after the judge by slope distance for similarity identification of logging curve. And in the further logging curve similarity compari-son has a very good application.
