摘要
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 North China, the Mesozoic petroleum supersystern of North China has been identified in this paper. In Mesozoic time the North China underwent three major stages of regional structure evolution, which, combined with the change of regional palaeoclimate, controlled, to a great extent, the development of sedimentary system and the enrichment of hydrocarbon generation materials and formed seveal regional petroleum generation-storage-accumulatio series of strata composed of many oil source rocks, which can be basically classified into Middle and Upper Triassic petroleum supersystem, Jurassic petroleum supersystem and Cretaceous peroleum supersystem. The Cretaceous one can be further divided into the dry--zone Lower Cretaceous petroleum system the humid-zone Lower Cretaceous petroleum system and the Upper Cretaceous petroleum system. This paper deals with the characteristics of Mesozoic petroleum supersystem in North China and presents some guides to and suggestions on exploring every petroleum supersystems.
