东营凹陷潜山成藏条件及成藏规律分析

Analysis on conditions and rules of reservoir forming of buried hill in Dongying sag.

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.
