Azimuthal moveout response of seismic waves in two-phase anisotropic media

XU Liying;MO Xiuwen;College of Geo-Exploration Science and Technology,Jilin University;  
Dispersion and attenuation occur while seismic wave travels through cracks filled with fluids,which lead to the anisotropism of seismic azimuthal travel time.Based on latest rock physics models,this study aims to simulate seismic azimuthal moveout responses(AMR) and analyze the factors affecting this attribute.By numerical modeling,it is found that the AMR is very sensitive to the parameters of the cracks,especially these related to fluid;therefore AMR has the potential to qualitatively or even quantitatively identify cracks.
