单程波法地震波衰减特征数值模拟分析
Numerical simulation analysis of the characteristic of seismic wave attenuation based on one-way wave equation
摘要
Abstract
The seismic wave attenuation study in non-uniform viscoelastic medium could reveal how absorption influences the characteristics of seismic waves. Based on the one-way wave equation, combining with viscoelastic media complex wave number theory, considering lateral variation and using split-step Fourier wave field continuation techniques, a seismic records formula concluding Q has been established which is suitable for the horizontal transmission medium. This method has been applied to four different Q-bearing models. The result shows: one-way wave equation has fast computed-speed, clear and simple wave field which is easy to analysis and establish the inversion algorithm; Q value effects the seismic waveform, energy, frequency and so on, which benefit the further research such as seismic energy compensation, improvement of seismic resolution, concealed reservoir discrimination.关键词
