摘要：

By the method of physical modeling combined with numerical simulation, the paper analyzes the P-wave azimuthal anisotropy phenomena in HTI media, focusing on the normal moveout velocity and travel time of target zone. The results show that theoretical values consist well with the experimental data, and HTI media can cause that V-nmo and travel time azimuthal change like an ellipse. Meanwhile, the ratio of maximum offset/depth and data azimuthal distribution are two geometry parameters having big impacts on azimuthal anisotropy analysis. The study needs reasonable geometry design and data with high quality.
