Oil and Gas Accumulation Conditions and Accumulation Mode in Llanos Basin,South America
摘要
Abstract
Llanos Basin is an important oil and gas rich basin in south America and even in the world which is located in the north of south American plate. Based on analysis of the Llanos Basin hydrocarbon accumulation,with condition,consideration of the tectonic evolution and sedimentation impact,the article reveals the hydrocarbon accumulation characteristics of Llanos Basin and establishes hydrocarbon accumulation mode. Llanos Basin has experienced three tectonic evolution stages of Pale-ozoic passive continental margin,Mesozoic back arc rift and Cenozoic foreland basins. There have developed multiple sets of hydrocarbon source rocks and reservoir cap combinations,various types of traps and complicated oil and gas distribution in the basin,and have good prospects for exploration and development. The hydrocarbon accumulation of the basin is characteristics of remote migration,mixed-source charging,broken sand-dimensional,continuous transporting and stepped-trapping accumu-lation;the oil and gas distribution of main production layer of Oligocene Carbonera Formation is characterized by large and medium-sized deep oil and gas fields formed by preferred trap of near hydrocarbon source rocks,and shallow-small-composite oil and gas fields formed by trap of far hydrocarbon source rocks. This knowledge obtained has important reference significance in further oil and gas discoveries of Llanos Basin.关键词
