【Abstract】 Deep layer seismic exploration gives new chanlegeand opportunity to the study on wave propagation. The main feather of deep layer seismic exploration is the influence of overburden, which makes the signal process unconvenietial. The wave equation datuming are a powerful tools to eliminate the influence of overburden . The high value of deep layer velocity and lateral inhomogdeurity makes it important that the large angle scattering and processing based on the elastic wave formula. We review the solution of deep layer seismic exploration, brief review the some aspect of Lie group method and elastic wave inversion in order to give some hint to the study.更多还原
