| VSP Data Processing in Anisotropic Mdeia |
| It is deduced in this paper theoretically the elastic wave equation in two dimen-sional EDA media, for which numerical modeling is carried out. We acquire the three com-ponent wave field section under point source exciting after a 30 rotation of the coordinate, and the four component synthetic recording, and we also acquire the split fast and slow S wave components, the delay time between them, and orientation of fractures through anal-yese of the sampled four components from two EDA media by means of synchronous rota-tion of the double source four components. Reflection energy is extracted from the split fast and slow S wave components,and then imagery processing is carried out for it using VSP-CDP transform method. |
