发表刊物:Journal of Applied Geophysics
摘要:Three dimensional numericalmodeling has been a viable tool for understandingwave propagation in realmedia.
The poroelastic media can better describe the phenomena of hydrocarbon reservoirs than acoustic and elastic
media. However, the numerical modeling in 3D poroelastic media demands significantly more computa-
tional capacity, including both computational time andmemory. In this paper, we present a 3D poroelastic
staggered-grid finite difference (SFD) scheme. During the procedure, parallel computing is implemented to
reduce the computational time. Parallelization is based on domain decomposition, and communication be-
tween processors is performed using message passing interface (MPI). Parallel analysis shows that the
parallelized SFD scheme significantly improves the simulation efficiency and 3D decomposition in domain
is themost efficient.We also analyze the numerical dispersion and stability condition of the 3D poroelastic
SFD method. Numerical results show that the 3D numerical simulation can provide a real description of
wave propagation.
