Abstract：On the basis of analysis of DMO in frequency domain of constant velocity and DMO with dip angle decomposition,the paper has preliminary discussion of DMO under any V(z) circumstances.Comparing with DMO in constant velocity,DMO in any V(z) is more close to real geologic condition,its pulse response is no more simple"SMILE"ellipse and difficult express in analytic expression in a condition of velocity field.It is showed by seismic data processing in Dagang District that DMO method for any V(z) is more suitable for severe variation in velocity and therefore has a better imaging results in diffraction and reflection that have steep dip angle and longer extension.
