Abstract

Based on three kinds of data, such as 3D Vertical Seismic Profile (VSP), multiple directional Walkaway VSP and full azimuth seismic data, the Vertical Transverse Isotropy (VTI) characteristics of plutonic igneous rock are studied, and an approach to calculate anisotropic parameter is presented. It is concluded that the target zone has apparent VTI characteristics. And then Addition of VTI anisotropic parameter can reduce the difference between forward move out and first break observation of reflection. It is also clearly that the anisotropic parameter estimated from multiple directional Walkaway VSP data is consistent with that from 3D VSP data.
