小波变换在基准面旋回划分中的应用

Divided Method of Datum Cycles Based on Wavelet Transform of Well - Logging Data

基于连续小波变换的特点，对GR测井信号进行小波分解，研究了使用信号经小波变换后的时频色谱图进行基准面旋回的划分与对比，最终结果表明该方法合理有效，具有可行性。

Based on the characteristic of continuous wavelet transform, wavelet decomposition of GR logging signals was carried out, then the coefficient curve of the wavelet transform was used to divide the datum cycles. The final results show that the method is reason- able , effective and feasible.
