摘要: 基于全球53个海相碳酸盐岩含油气盆地199个大中型油气田的最新资料,根据油气成藏体系理论的分析原则,将成藏体系的“源-位”分类方案应用于海相碳酸盐岩大中型油气田,统计分析了这些油气田中单源一位、单源二位、单源三位、二源二位、二源三位和三源三位6类成藏体系类型油气田的分布和储量特征,厘定海相碳酸盐岩盆地油气富集的主要成藏体系类型,揭示其对海相碳酸盐岩盆地油气富集的控制作用。结果表明,海相碳酸盐岩大中型油气田中最主要、最普遍的成藏体系类型为单源三位,这类成藏体系富集的油气储量最多,其次为单源二位和二源三位,而归属于其它成藏体系类型的油气田储量不大,个数亦相对较少,分布也较为分散。单源二位是最优越的成藏体系,具有规模性的成藏效应,但后期需较好的保存条件。此外,单源一位更多地表现为非常规性质,成藏体系的三大要素集于同一套岩层,但这种成藏体系在海相碳酸盐岩层系中发现的最少。

Abstract: A classification of petroleum accumulation systems (PAS) of marine carbonate fields was attempted by using the latest data of 199 medium to large marine carbonate fields from 53 petroliferous basins around the world and a “source-element” classification scheme.The result shows that PAS of the fields can be categorized into six types: one source-one element,one source-two elements,one source-three elements,two sources-two elements,two sources-three elements and three sources-three elements.The distribution patterns and characteristics of petroleum reserves for each of the 6 types of PAS were investigated and the dominate types with high hydrocarbon richness in marine carbonate petroliferous basins were identified,and their controls on hydrocarbon enrichment were revealed.Statistical analytical results show that one source-three elements PAS not only hosts the largest share of petroleum reserves but also occurs the most widely.It is followed by one source -two elements and two sources-three elements PAS.For other types of PAS,both the reserves and the numbers of occurrence are relatively small.One source-two element PAS is the most promising among all the types but it requires more favorable later preserving conditions.One-source-one element PAS presents itself mostly as unconventional reservoirs but is rarely found in marine carbonate rocks.
