The high-precision finite difference method for seismic forward modeling

摘要

The Arbitrary Difference Precise Integration Method (ADPI) for solving the wave equations is given in this paper. We present the processing about the formula deduced of ADPI, and discuss the boundary conditions. The result of theory analysis and examples of real data for seismic forward modeling indicates that APPI method has better precision . The tests of real modeling data show that ADPI method is suitable for the difficult complex surface and substructure area.
