| 摘 要： | 就孔隙度曲线含有非地质因素的噪音这一特点,提出采用小波变换的新方法。该方法以一维小波去噪方法和小波包去噪方法为主,减少噪声信号φs的部分值、处理结果表明,经小波变换后的曲线噪声得以压制,质量得以提高,能更好地与其它测井曲线配合进行综合解释。

| Abstract: | Wavelet transform method was used in view of that there exist noise originated from non-geological factors on porosity profiles. This method, which takes 1-D wavelet noise elimination and wavelet packet noise e-limination as its principle elements, can reduce the part value of noise signal φs. Processing results indicated that porosity profiles had less noise after wavelet transform and could be more effectively used in comprehensive interpretation when combining with other logs. |
