摘要

地震信号在频率域和时间域表现出不同的特征，利用频率域的地震信号，可以更好地进行储层预测。利用傅立叶变换和小波变换等数学工具，研究了地震数据在频率域的特征，开发出了小波域时频分析技术、分频地震相技术、频谱相关技术、频谱分解储层成像技术等多种频率域储层预测技术，将这些技术在实际地震资料中进行了应用，取得了较好的效果。

Abstract

The features of seismic signals are different between time and frequency domains. We can make reservoir prediction better with seismic signals in frequency domain. The features of seismic data in frequency domain are studied with mathematical tools, such as Fourier transform and wavelet transform. And many reservoir prediction technologies in frequency domain are developed, such as the technology of time\|frequency analysis in wavelet domain, frequency division seismic facies, frequency spectrum correlation, reservoir imaging of frequency spectrum decomposition. These technologies are applied to practical data and have a good effect.

Key words： Reservoir prediction; Time\; frequency analysis; Seismic facies; Frequency spectrum correlation; Frequency spectrum decomposition
