It is confirmed by drilling and oil testing that there are many vertical oil & gas layers,many oil & gas types and complex accumulation patterns in Shengbei area.This paper analyses the correlation between known oil-gas reservoir and source-reservoir-cap,the lithology of upper strata and the oil-gas reservoir as well as its production,the position of oil-gas reservoir and the structure in Shengbei area,figuring that J_2q is the major stratum in oil & gas assemblage of self-generation and self-accumulation,and J₃k, K₁ and K₁lshould be regarded as the major prospect  object in the oil & gas assemblage of injection migration; It also concludes th at most oil　&　gas is stored at the top of sand unit and its production has clo se relations with the upper cap, and that the geological strata will ascend with  structural position. These conclusions have certain significance to the cogniti on of the vertical distribution of oil & gas in the whole basin and target evalu ation and optimization, and can well guide hydrocarbon detection by integrating  multiple seismic attributes geologically.
