摘要:

波斯湾盆地、东委内瑞拉盆地和西加盆地是全球油气最富集的前陆盆地。根据最新油气地质资料分析,它们的油气分布特征及资源结构存在明显差异。区域上,3个前陆盆地的逆冲褶皱带和前渊一斜坡带均有油气分布,但油气主要分布于前渊一斜坡带。层系上,波斯湾盆地91.0%以上的油气储量分布于被动陆缘层系,而东委内瑞拉盆地和西加盆地的油气则主要富集于前陆盆地层系。波斯湾盆地的油气资源以常规油气为主,而东委内瑞拉盆地和西加盆地则以非常规重油和天然沥青最为富集。区域性盖层与输导体系的配置关系是控制前陆盆地油气资源结构的主要因素。

Abstract:

The Persian Gulf Basin,Eastern Venezuela Basin and Western Canada Basin are the richest petrolife rows foreland basins in the world.  Analyses of the up-to-date oil and gas geological data indicate that there are significant differences in oil and gas distribution features and hydrocarbon resource mixes among the three foreland basins.  Within the foreland basins,oil and gas are widely distributed throughout both the thrust-fold beltand foredeep一slope,but the discovered reserves are mainly concentrated in the foredeep-slope. Stratigraphical1v,passive margin tectono-strata host over 91.0% of the discovered reserves in the Persian Gulf Basin while foreland sequences are the major reservoir intervals in the Eastern Venezuela Basin and the Western Canada Basin.  The petroleum resources of the Persian Gulf Basin are dominated by conventional oil and gas while the Eastern Venezuela Basin and the Western Canada Basin are endowed with unconventional heavy oil and natural bitumen. The spatial configuration relationship between regional seals and petroleum migration pathways controls the different mixes of hydrocarbon resources in the foreland basins.
