摘要

谱分解技术可将地震数据从时间域转换到频率域，从而获得在时间域无法得到的一些信息，提高地震资料预测薄储层及岩性圈闭的能力。先进的谱分解技术是时频分析技术。首先阐述了时频分析技术的基本原理、方法及其对地震资料处理与解释的重要意义，继而论述了近年来时频分析技术在地震勘探中的具体应用领域，包括谱分解、谱反演、波形分类和分频处理等，并对其应用进行了展望。

Abstract

Spectral decomposition techniques can be used to extract some useful information in time-frequency domain which can not be found in conventional time domain, and improve the prediction ability of thin reservoir and lithologic traps. The key point of spectral decomposition is time-frequency analysis. This paper expounded the principle and method of time-frequency analysis technique and its significance to seismic data processing. Some application cases of time-frequency analysis technique in seismic exploration were presented to illustrate the progress of the application of time-frequency analysis in seismic exploration, including spectral decomposition, spectral inversion, waveform classification and frequency splitting processing. From the process we can see that the application of time-frequency analysis technique
in seismic exploration has a fine prospect.

Key words： petroleum geologic characteristics; exploration prospect; Rovuma Basin in East Africa
