This paper elaborates geochemical meanings and geologic significance of pyrolysis parameters of reservoirs. Combined with the characteristics of pyrolysis parameters of reservoirs in Shenjiapu area, the paper analyzes the properties of crude oil and the change of oiliness in the vertical direction in Shenjiapu area, Pointed out the main oil layer of the date V oil group, tested the effectiveness of perforation, put forward the section of the shotgun. The analysis results show that the crude oil in Shenjiapu area has high density and high viscosity, and belongs to heavy heavy oil. The oil content of reservoir becomes worse with the increase of depth in the longitudinal direction, from oil layer to oil-water layer.
