Abstract:Converting dip reflector time to the corresponding horizontal reflector time is called DMO correction, The DMO method is conspicuous because it takes less time than prestack migration but obtains the geologic effect which is as good as that of prestaek migration in a complicated area. The DMO method can be performed in time domain or in frequency domain; and in the time domain, both the integral methud and the difference method can be used, The theory and practice show that the integral DMO in time domain has some advantages:easy operation, flexible application and less operation amount, The operation time will be largely reduced when a good control of dip γ (T0, x) is made in the integral DMO method.
