| 中文摘要: |
| 以琼东南盆地深水区中央峡谷黄流组一段和莺歌海组二段为例，分析希尔伯特-黄变换在层序地层划分中的应用效果。通过对自然伽马曲线进行经验模态分解，得到不同频率域的本征模态函数，根据这些本征模态函数的周期性振荡特征与各级层序界面之间建立的对应关系划分各级层序。结果表明：希尔伯特-黄变换适用于长期、中期和短期基准面旋回的划分，该方法为琼东南深水区的层序地层划分提供了一个重要的辅助手段。 |
| 英文摘要: |
| The first member of Huangliu formation and the second member of Yinggehai formation of the central canyon in deep-water area of Qiongdongnan Basin are taken as the example to analyze the application of Hilbert Huang Transform to sequence stratigraphic division. Through decomposing the natural gamma curve by empirical mode is obtained intrinsic mode functions of different frequency domains, and then divided grade sequence according to the corresponding relationship established between the periodic oscillations of the intrinsic mode functions and the sequence boundaries. The results show that:Hilbert Huang transform is suitable for the long, medium and short term base-level cycles and provides an important supplementary mean for the sequence stratigraphic division in deep-water area of Qiongdongnan Basin. |
