A comprehensive program for staggered-grid finite-difference wavefield simulation and AVO attribute analysis in two-phase media, featuring multiple staggered-grid schemes with varying accuracy levels, eigenvalue-based boundary absorption conditions, elastic parameter calculation modules for biphasic materials, and AVO attribute computation and analysis tools.
This project implements wavefield simulation for two-layer geological models using finite difference methods to process multi-component seismic records. The simulation leverages anisotropic information to effectively reduce ambiguity in P-wave exploration, quantitatively characterize fractured reservoirs, and improve structural imaging in areas with poor P-wave data quality. It generates multi-wave profiles with higher resolution than conventional P-wave methods, facilitating the study of subtle structures, faults, and fracture systems for practical hydrocarbon exploration applications.
