摘　　要：在系统分析储层、盖层、油源条件及潜山圈闭供油通道的基础上 ,阐述了东营凹陷潜山油藏的成藏条件 ,并探讨了油气富集规律 ,提出了拆离断层带、张扭断裂带、缓坡带 (渐次升高型和渐次降低型 )、褶皱披覆构造带四种潜山聚油模型 ,总结了潜山圈闭油气富集的主要条件。On the basis of systematic analysis of reservoir, caprock, oil sources condition and oil feeder channel of buried hill trap, the reservoirforming conditions of the buried hill type reservoir are set forth and oilgas enrichment rules of the reservoir are discussed. Four types of oilaccumulation models including decoupling fault zones, transtensional fault zones, ramp zones (gradually raising type and gradually dropping type) and fold drape structural belts are advanced. The dominant conditions of oilgas enrichment of the buried hill trap are summed up.
