Abstract

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
