钻井、试油成果证实,胜北地区油气的纵向分布层位多,油气类型多,成藏规律比较复杂。通过对胜北地区已知油气层与区域生储盖、上覆地层岩性与油气层和产量、油气层位置与构造相互关系的分析,认为J2q油气层是该地区自生自储式含油气组合的主力油气层,在下生上储式含油气组合中,应将J3k、K1、K1l油气层作为主要勘探对象;油气大多保存于砂层组的顶部,油气层产量与上覆盖层之间有密切的关系;随着构造位置的升高,油气层地质层位也依次升高。

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.
