摘要/Abstract

摘要： 发育在南美西缘的次安第斯弧后前陆盆地群为南美重要的油气产区,其形成于3 个大的构造背景之下：北部为加勒比板块演化叠加安第斯前陆挤压;中部的次安第斯前陆盆地长期处于冈瓦纳古陆的大陆边缘环境,之后受到大洋板块的俯冲和安第斯山脉的隆升和冲断;南部巴塔哥尼亚各盆地的形成演化更多地受到冈瓦纳古陆裂解和大西洋形成的影响。综合安第斯山脉的形成演化以及各盆地的构造演化和石油地质特征,将其划分成6 段。

Abstract: Sub-Andean retro-arc foreland basins in the western margin of South America are important petroleum accumulation and production zones, and develop in three different tectonic settings: evolvement of Caribbean plate superimposed Andean-type foreland compressive deformation in the north; Sub-Andean foreland basins were in long-term the Gondwana continental marginal setting, subsequently subducted by oceanic plate and thrusted by Andean orogenesis in the middle; the shapes and evolvement of basins in Patagonia were more influenced by Gondwana breakup and opening of Atlantic in the south. Based on the evolvements and petroleum characteristics, the sub-Andean retro-arc foreland basins in the western margin of South America could be divided into 6 segments.

Key words: western South America, sub-Andean, retro-arc foreland basins, segment characteristics
