摘要： 谱分解技术是一项基于频率谱分解的解释技术,根据地震反射中各频率成分对应的调谐振幅不同,计算出相应的储集层的厚度。小波变换是谱分解的重要方法,将该方法运用到地震物理模型中,不仅可以有效地预测储集层的厚度,而且可以描述储集层的横向变化、沉积相带演变。

Abstract: Spectral decomposition technique can be used to accurately calculate the reservoir thickness according to different tuning amplitudes in seismic reflection corresponding to components of different frequencies. Wavelet transform is an important method for spectral decomposition. Application of it to a seismic geophysical model can not only effectively predict the reservoir thickness, but also describe the lateral distribution characteristic of reservoir and the evolution of sedimentary facies.

Key words: spectral decomposition, tuning amplitude, wavelet transform, seismic model
