摘　　要：钻探表明,车排子凸起具有多含油层系、多油藏类型和多油质品位等“三多”成藏特征。通过地层沉积、构造演化和油源对比分析,认为“三多”成藏特征与构造格架的分割、沉积旋回和成藏期次的控制和多向油源充注密切相关,并且由于车排子凸起南部南偏东方向古山脊的存在和北部东南方向古山梁的发育,形成了南部古近-新近系浅层以稀油聚集、晚期成藏为主,北部侏罗系-石炭系以后期改造、稠油分布的成藏特征。It is indieated from drilling that Chepaizi swell is eharaeterized by muhiple oil-bearing zones, muhiple reservoir types and muhiple oleaginous grades. The ＂tri-muhiple＂ charaeteristics are related to the cutting of struetural framework, the control of sedimentary eyele and hydroearl）on-accumulatlng stage and the eharging of muhi-direetlonal oil sources in terms of eorrelatlon and analysis of sedimentary strata, structural evolution and source rocks. The existence of paleo-ridge in SE direction of southern Chepalzl swell and the development of paleo-ridge in ES direction of northenl Chepalzl swell allow the feature to be different, that is, in southern part the shallow Tertiary reservoir is dominated by late stage light oil accumulation and in northern part the Carboniferous-Jurassic reservoirs are eharacterized by heavy oil distribution and late reeunstruetiun.
