- W2365845701 abstract "A wave equation based prestack time migration scheme in anelastic media is proposed.Frequency independent Q law and complex phase velocity are used to describe the absorption of seismic energy.Methods for wavefield extrapolation and prestack time migration in complex anelastic media are developed based on phase shift method and stationary point theorem.The synthetic dataset are used to demonstrate that the prestack time migration in dissipation media not only can improve the ability of imaging complicated structure when the velocities mildly vary.The migration section of a 2D dataset proved that incorporation compensation for absorption and dispersion into time migration can effective resume the high frequency information of deep reflection.The spatial wavelet was compressed;the band of frequency was extended;the amplitude of record was increased;the revolution of seismic profile was enhanced." @default.
