Abstract:

Finite-difference forward modeling method with body-fitted can accurately simulate wavefields in presence of topography, meanwhile, the computational efficiency is relatively high. Therefore, it is a prospecting method for dealing with the western complex surface. The collocated-grid and standard staggered grid are often used to solve wave equation. However, they show many problems when the above two grids are extend to body-fitted grids. By introducing the fully-staggered grid to curvilinear coordinates, the proposed method can avoid not only the interpolation error when standard staggered grid are used, but also the high-frequency oscillations with the collocated-grid. Thus, it can improve the simulation accuracy and reduce the complexity of the algorithm degrees. To satisfy the free surface boundary condition, we use the traction image method to calculate the velocity components, the method also uses the velocity of free boundary conditions with compact staggered difference format to update the stress components. Model tests show that the proposed method can obtain the good results. And then, we mainly study the influence factors of forward modeling algorithm by a fully staggered body-fitted grids, such as, the orthogonality of grids, the grid spacing change, and the skewness of meshes.Finally, we obtain some conclusions as follows:the algorithm is not sensitive to the orthogonality of grids;the grid spacing changing can lead to false reflection;the result of simulation is not affected by the skewness of different types of grids.

Key words: irregular free surface, body-fitted grid, full staggered-grid, forward modeling, factors
