依据中国北方中生代含油气盆地的特征和演化,划分了中国北方中生界石油超体系。中国北方区域在中生代经历了三大区域构造演化阶段,在此背景下,区域古气候条件的变迁在很大程度上控制了中生代沉积体系发育和生烃物质的富集程度,形成由多个生油岩体构成的区域性生、储、聚油气层系,大体可分为中-上三叠统石油超体系、侏罗系石油超体系和白垩系石油超体系,其中白垩系还可再分为干旱区下白垩统石油体系和潮湿区下白垩统石油体系及上白垩统石油体系。探讨了中国北方中生界石油超体系的特征,提出了勘探各石油超体系的方向和建议。
Based on the characteristics and evolution of Mesozoic petroliferous basins in northern China, the Mesozoic petroleum super-system in northern China was divided. Under the background of the Mesozoic tectonic and evolution stages in the Mesozoic in the northern China, the change of regional paleoclimate conditions to a large extent controlled the development of Mesozoic sedimentary system and the enrichment of hydrocarbon generation. The regional genera, reservoirs and poly-hydrocarbon reservoirs formed by oil and rock mass can be roughly divided into the Middle-Upper Triassic petroleum super-system, the Jurassic petroleum super-system and the Cretaceous petroleum super-system, in which the Cretaceous can be subdivided For the arid region Lower Cretaceous petroleum system and wet zone Lower Cretaceous petroleum system and the Upper Cretaceous petroleum system. This paper explores the characteristics of the Mesozoic petroleum super-system in northern China, and proposes the direction and suggestions for exploration of each petroleum super-system.
