摘　　要：Under the condition of conventional seismic data, because the thickness of the whole stratum of the second member of Shahejie Formation in the south is reduced, it is wedge-shaped in the south, and the shielding effect of the interface between the overlying sand and the bottom layer or the weak seismic reflection signal, it is difficult to identify the overbreak line, which seriously affects the exploration and development of the second member of Shahejie Formation. Based on this, on the basis of target processing of seismic data and cross-well correlation of logging sequences, and combining with seismic structural attributes, the location of stratigraphic superstripping lines is preliminarily determined, and then the accurate location of stratigraphic superstripping lines is finely determined by using the included angle extrapolation technique and seismic stratigraphic method for interactive verification.
