摘要

针对地震波在较为复杂的孔隙介质结构体系中波场随结构的微变而发生变化的情况，研究孔隙介质中表征介质结构的几个参数对各类地震波传播的影响作用。首先建立了各向同性弹性孔隙介质模型, 并导出了相应的弹性波波动方程，采用高阶交错网格有限差分法进行了正演模拟，同时分析了孔隙度、黏滞性、渗透率3个孔隙结构参数对波场特征的变化影响。该研究有助于加深对地震波在实际复杂介质体系中传播规律的认识。

Abstract

For the case of seismic waves in a more complex architecture porous medium wave field occurs slightly changed with changes in the structure, several parameters characteristics of the structure of the media which influence on various types of seismic wave propagation were studied. Firstly, the article establishes the isotropic elastic porous medium model, derive the corresponding elastic wave equation, and uses high-order staggered-grid finite difference method for forward modeling, the article also analyze the pore structure parameters such as porosity, viscosity and penetration influence on the wave field characteristics were also analyzed. At the same time, the study analyze the influence of porosity, permeability and viscosity on phase velocity and attenuation coefficient was analyzed in the stady. The results showed that the influence on attenuation coefficient was more sensitive than that on phase velocity. This study helps to deepen the understanding of seismic wave propagation in the practical system of complex medium.
