摘　　要：以文明寨、桥口、胡-庆及白庙等几个典型的复杂断块油气藏为例分别归纳总结了中央隆起带、西部斜坡带和东部陡坡带3个区带的油气成藏规律和模式,初步提出了东濮凹陷复杂断块油气聚集规律和复式成藏模式。主力生油洼陷的分布决定油气的运聚场所,大型古隆起和宏现背斜构造背景控制油气分布与富集,区域性盖层和生储盖组合关系决定油气纵向分布和富集程度,大型构造背景、多生储盖组合与复杂断裂体系形成复式油气聚集区。According to the characters of typical several oil and gas reservoirs in the area of Wenmingzhai, Qiaokou, Huqing and Baimiao, The law and model of reservoir-formation is summed up in the region of central trend, slope in the east and west flank respectively,The law and complex model of reservoir-formation is established about complex-fault block in Dongpu depression finally. The distribution of the main source sags determines the place where the oil and gas are accumulated. The ancient giant highs and macro-anticline structures control the distribution and richness of oil and gas. Regional cap and reservoir and source determine the distribution of oil and gas vertically. The background of great structure and multiple assembly of reservoir and cap and complicated rifting systems are the base to form complex oil-gas accumulation zones.
