摘　　要：南美西部主体为安第斯造山带,该造山带东侧亚安第斯地区由南至北分布有大量重要的含油气盆地,但由于各盆地演化历史及大地构造背景不同,其源岩、储集岩、盖层及圈闭条件也不尽相同,进而影响其油气潜力。通过综合分析前人在该区的基础地质及油气地质研究成果,总结该区大地构造分区及盆地演化,比较各盆地油气成藏的主控因素及油气潜力,进而明确勘探方向,为我国在该区的油气战略选区提供依据。The main structure is Andes orogenic zone in western South America,by the east,there are 19 retroarc foreland basins longitudinally in Sub-Andean region.The basins are important petroliferous area.As different geotectonic evolution history,the conditions of generation - accumulation -seal assemblage would be diversity,and then oil potential were influenced.By integrating basic geology and petroleum research work,analysing geotectonic area division and basins evolution of this area,comparing main controls to preservation and oil potential of the basins,then the exploration direction has been determined,which will provide reference for strategic exploration areas in our country.
