【摘要】 濮卫环洼带是东濮凹陷的主要油气富集区。剖析了该区油气成藏的基本条件及成藏规律,探讨了断裂活动因素对油气富集控制的4种方式。研究结果表明,该区主要发育构造油气藏、岩性油气藏及构造-岩性复合油气藏;其生烃、排烃、油气运移和圈闭形成之间具有良好的时空配置关系,是油气大规模聚集和成藏的关键因素。更多还原

【Abstract】 Oil-bearing belt around Pu - Wei Subsag is the main oil and gas enrichment zone in Dongpu Sag. The basic conditions and rules of oil and gas reservoir formation in this area are analyzed. Four ways of the effect of faulting movement elements on the oil- gas enrichment are discussed. Research results show that structural, lithologic and structural-lithologic oil-gas reservoirs develop mainly in this area. The hydrocarbon - generation, hydrocarbon - expulsion and oil - gas migration have good space -time relation setting with traps,which is the key factor of the oil- gas accumulation and reservoir-forming at large scale.更多还原
