HHT方法在研究地震旋回体中的应用
|
摘要
HHT(Hilbert-Huang变换)是一种近年才发展起来的非线性信号处理方法,具有明确的物理意义、高度的精确性和自适应性,但在地震信号处理中尚未得到广泛的应用。简要介绍了HHT的方法原理,然后分析了模型信号和地震旋回体的HHT时频谱。结果表明:HHT对模型信号的识别能力强,且不同类型地震旋回体与其HHT时频谱之间存在对应关系,这为地震层序的划分以及进一步的沉积相分析提供理论依据。
HHT(The Hilbert-Huang transform) is a signal analysis method developed in recent years,which has clear physical meaning,high-degree accuracy and adaptability.In this paper,the principle of HHT is introduced,and HHT spectra of both model signals and seismic cycles are analyzed.The result suggests that this method can perfectly distinguish the model signals,and different type seismic cycles are correspondent to their HHT time-frequency spectra.This provides theoretical evidences for seismic sequences identification and sedimentary faces analysis.
