Abstract：Yingtai area is one of the areas in the east of China where the exploration has prominent effect.The area has good stratigraphic physic condition,high production capacity.The influence of throw,extension of fault and thickness of sand body on reservoir are obvious.Oil gas accumulation mainly are concentrated into structural trap with low relief.The reservoirs mainly are structural lithologic composite reservoirs.According to the petroleum geologic characters of the region and fully using 3 D seismic data,the paper uses 3 D visualization interpretation technique,coherent body and stratigraphic dip detection technique,reservoir prediction technique and multi contribution model constrained inversion for interpretation of main targets and appreciation of traps.The applied techniques are practical and effective after drilling examination,having generalized value.
