The review of the finite-difference elastic wave motion modeling

FENG Ying-jie,YANG Chang-chun,WU Ping(Institute of Geology and Geophysics,Chinese Academy of sciences,Beijing 100029,China)  
The numerical seismic wave propagation modeling is a powerful tool in the oil exploration,such as the date collection,the processing and the interpretation and so on.It can not only find out the properties of the media,but also check the validity of processing methods,recognize the law of the wave propagation.In all the numerical methods,the finite-difference method is more useful with its advantages,such as high precision,flexibility,costless.In this paper,several parts of the finite-difference method are discussed,such as the finite-scheme,the source problem,the boundary condition and the numerical dispersion dumbness.
