Seismic wave field numerical modeling with high-order finite-differential method
摘要
Abstract
Based on seismic wave equation and finite-differential method, seismic wave field numerical modeling with high-order staggered mesh is studied for different complicated geographical mode. First, seismic wave equation is derived to obtain one-order stress-velocity equation, then, the equation is discretized in time and space by staggered mesh finite-differential method. This method is used to simulate three-level strata sloping downward model, fault model and oil layer model and the differential order of the simulation accuracy is discussed. The results indicated this method is suit for simulating non-homogeneous media and complicated geographical mode with high accuracy and efficiency.关键词
