| 摘 要： | 利用小波变换的多分辨分析特征，采用几种常见的小波函数(Harr小波，Daubechies小波，Symlet小波，Dmeyer小波)，分别对自然电位、自然伽马、视电阻率等测井曲线进行小波变换，发现在某一个尺度范围内可以识别出层序地层的准层序单元。利用该方法对胜坨油田5口井的测井曲线进行识别，与人工划分结果的比较表明，利用Symlet小波对视电阻率曲线进行分解识别的效果最理想。图1表1参6 |

| Abstract: | According to the character of multi-resolution analysis, several common wavelet functions such as Harr, Daubechies, Symlet, and Dmeyer function are used to transform SP, GR and RT. It is concluded that the para-sequence units of stratigraphy sequence can be identified in certain range. By this method, the well log curves of Well T715, T711, T76, T79, T762 in Shengtuo Oilfield have been identified. The statistics suggests that the best result is the symlet wavelet. |
