Abstract:

According to elastic theory and generalized Hooke’s Law, the scalar wave equation in isotropic media is deduced. The solution of the equation is given by the difference. Author gives the stability condition of the difference equation. Referring to the previous research results, the absorbing boundary condition is injected. During the migration, the underground images is identified by using the eikonal equation solution. At last, author uses this method to process the seismic forward data and real seismic data.

Key words: Triassic, Yanchang Formation, sedimentary microfacies, Yanchi-Dingbian area
