摘要
本文给出了一种时频分析资料处理及显示的新方法，该法是在深入时频分析的基础上，首先寻找并计算出能表征瞬时频谱主要特性的主振幅和主频率，然后在时空域形成主振幅剖面和主频率剖面。计算及应用结果表明，本文给出的用主参数剖面进行时频分析与滑动谱时频分析相比有更多的优越性：便于显示和解释各种地质现象。尤其对断层和横向地层厚度或岩性变化现象的显示和解释更为有利；可节省大量的计算机资源，出图速度可提高几十倍，上百倍，适合批量生产。
A new technology for seismic data processing and display in time frequency(T-F)domain is presen ted in this paper. Based on the T-F analysis, Main amplitued and main frequen cy sections which characterize the seismic instantaneours spectrum can be ealculated and displayed in time-space domain。 Using seismic main characteristic sec-tions has more advantages than running spectrum sections:We ean easily identify and interpret structures,especially faults and changes both in thickness and lithology of layers;can save much more computing time and computer resources.
