Abstract

Chen, X., Han, L., Yang, H. and Shang, S., 2015. qP wave numerical simulation in viscoelastic VTI media by one-way wave equation. Journal of Seismic Exploration, 24: 439-454. Theoretical and practical studies show that the subsurface media has not only the anisotropic properties but also the anelastic properties. These properties are commonly denoted by the viscoelastic model. The conventional elastic isotropic seismic wavefield simulation could not provide sufficient foundations for the modern acquisition, processing and interpretation of the seismic data. In this article, we proposed a new qP wavefield modeling method in the viscoelastic VTI media by using the one-way wave equation. The one-way wave equation method can simulate the seismic reflection wavefield fast and accurately even in complex structure areas. The method has many advantages compared with the full-way wave equation method especially in the large-scale simulation problems, such as high calculating efficiency, low memory requirement and no interference of direct and multiple waves.
