| 摘 要： | 小波变换是进行测井层序地层研究的重要辅助手段。以辽河盆地东部凹陷XK地区沙河街组地层沙三段为例,对测井曲线应用一维连续小波变换,并借助于小波变换后的某个尺度下的小波系数曲线和在所有尺度下的小波系数谱,对该地区沙三段地层进行了层序地层研究,并建立了该地区沙三段层序地层格架,总结了小波变换后得到的小波系数曲线与小波系数谱中各自的变化情况所对应的地质意义。

| Abstract: | Wavelet transform is the important supplementary means of log sequence stratigraphy study.This paper takes Shahejie Formation of the Xinkai-dongjiagang area in East Depression of Liaohe Basin as an example,one-dimensional continuous wavelet transform was applied on the log curve,with the help of the wavelet coefficients curve from the transform and wavelet coefficients spectrum in all scales,studying the characteristics of the sequence stratigraphy of the Shahejie formation in this region,and then building the sequence stratigraphic framework of Shahejie formation.Conclusions were obtained： different changes in wavelet coefficients curve and wavelet coefficients spectrum have different geological significance. |
