Hydrocarbon differential accumulation of foreland basins in western South America and its controlling factors

摘要: 以IHS2009资料库14个主要盆地4 400余个油气藏资料为基础,总结了南美西缘前陆盆地油气聚集特征,并对油气差异富集因素进行了分析,结果表明:(1)南美前陆盆地油气具有明显的分段性差异富集特征:①平面上油气主要富集在北段盆地(可采储量占总量85%),中段(6.9%)和南段盆地(8.1%)油气富集程度低;②纵向上北段盆地油气富集在上部白垩系和第三系储集层,中段盆地油气富集在侏罗系以下储集层,南段盆地富集在侏罗系和白垩系地层。(2)石油地质特征的分段性是油气差异聚集的主要控制因素:①烃源岩分段性发育决定油气平面富集位置;②储盖组合发育层位的分段性决定油气纵向富集层段。Abstract: In order to study the hydrocarbon differential accumulation of the foreland basins in the western South America and its controlling factors, we collected over 4 400 data of 14 foreland basins within IHS2009 database. Several conclusions were made as followed. (1) The foreland basins have distinct segmental accumulation characters. Hydrocarbon mainly accumulated in the north, accounting for 85% of total recoverable reserve, while in the center and south, only 6.9% and 8.1%, respectively. Vertically, hydrocarbon mainly distributes in the Upper Cretaceous and Tertiary reservoirs in the north, below Jurassic in the center, and in Jurassic and Cretaceous in the south. (2) The segmental features of petroleum geology controlled the differential accumulation of hydrocarbon. The segmental development of source rocks determined the plane enrichment of oil and gas. The segmental development of reservoirs and cap rocks controlled the vertical distribution of hydrocarbon.
