Abstract：In order to further explore shallow targets in Structure No.4,Nanpu area,we discuss in the paper geological problems of qualitative or quantitative channel description in Minghuazhen Formation.Interpretation tools provided by GeoEast system are applied to seismic data in the area under the guidance of the exploration theories of litho-stratigraphic hydrocarbon reservoir in enriched depressions.Seismic identification and prediction from macroscopic to microscopic observation,step control and step approximation are adopted.The shallow channel sand identification has been well enhanced based on the study results.Minghuazhen Formation in Structure No.4 is identified and eva-luated.The favorable targets of stratigraphic-lithologic traps are indicated in this area,and also provides a reference for similar areas.
