Abstract:The.method of employing DIX formula to get interval velocity from the spectrum of horizontally stacking velocity is only applicable to harizontal layered-medium, A new method must be sought for layered-medium with arbitrary dip, This paper presents the velceity analysis method for mufti-layered medium, which can be used to scan the 2-D dip and velocity in depth domain in accordance with the layer-by-layer recursion formula derived from CDP time-distance curve equation of the dip formadons of 2-D arbitrary plane, Then, the sign-bit can be detected by using generalized likelihood methed in order to get the velocity, dip and depth for each layer.
