After the analysis it was concluded that the mean velocity fluctuations of the strata under Jidike Group in this working area could be divided into three zones: the minor velocity fluctuation zone in southern Dalaoba tectonic belt, the steep velocity fluctuation zone of the foreslope in middle YK structure and the zone from the bowtype thrusting tectonic belt in northern Qiulige to the minor velocity fluctuation zone in YK tectonic zone. On the basis of a good command of the regular patterns of the velocities in vertical and horizontal dimensions in the investigating area, the stack velocity was interpreted in a interactive mode by using the Depthteam Express modelling package of the Landmark system, converting the stack velocity into mean velocity by means of Dix formula. Based on the well drilling layering data, the velocity correction was executied to get the final corrected velocity model by using the Kriging Correction. By using this velocity model, we did the time to depth conversion and obtained the final depth structural map. After mapping by using the variable velocities, we came in for the display of the tectonic map of the seismic data.
