description The invention provides a method of correcting the stack velocity among different treated sides, belonging to the exploration earthquake data processing field. The method comprises: a first step of inputting a VT logarithmic function Vold (T0) and the vertical time shifting amount delta t of a stack velocity analysis processing surface at a position; a second step of for all VT logarithmic functions Vold (T0) in a work area, calculating a VT logarithmic function Vnew (T0) corresponding to a new reference surface, wherein Vnew= Vold/ radical sign (1+deltat/T0), and T0 is the vertical double pass travel time of reflection waves; a third step of outputting the Vnew (T0) corresponding to a new reference surface corresponding to the analysis position of all VT logarithmic functions Vold (T0) in a work area; and a fourth step of establishing a velocity model by using the VT logarithmic function Vnew (T0) corresponding to a new reference surface .
