南美洲油气地质特征及资源评价
Petroleum Geology and Resource Assessment in South America
摘要
Abstract
The paper has comprehensively summarized the petroleum geological characteristics of South A-merica through the systematic analysis of 28 main petroliferous basins in South America, which are ①development "two" times,"two types" of source rocks; ② single reservoir type, oil gas concentrated in the Cretaceous and Tertiary reservoirs; ③ developing four kinds of accumulation models, the western foreland basins developing steep short distance vertical migration accumulation model and slope distance lateral migration reservoir forming pattern; eastern continental passive margin basins developing of post salt "fault + salt diapir" migration pattern and pre salt "carbonate + bury hill" migration pattern; ④ In plane, oil and gas mainly distributing in two belts distribution, concentrating in two centers. At the same time, the paper evaluates the source potential of South America by taking a role of basic assessment unit. The predicted undiscovered recoverable resource of South America is 214 065 MMBOE, which mainly concentrates in the eastern passive margin basins and western foreland basins. The eastern Venezuelan Basin, Maracaibo Basin, Santos Basin and Campos Basin are the four basins with large predicted source.关键词
