摘　　要：针对亚诺斯盆地目前勘探不够系统,油气成藏特征不明确的问题,本文在亚诺斯盆地构造演化史及构造划分的基础上,总结亚诺斯盆地的油气成藏生储盖条件,揭示亚诺斯盆地油气成藏特征,对盆地圈闭特征、成藏模式、成藏组合及油气分布规律进行深入分析,探讨其资源潜力及勘探前景,指出盆地下一步勘探方向。研究表明,亚诺斯盆地主要经历了克拉通边缘盆地、中生代弧后裂谷盆地和新生代前陆盆地3个构造演化期;盆地内发育多套烃源岩及储盖组合;圈闭类型丰富多样,主要沿西北-东南呈条带状分布于盆地前渊带和斜坡带;盆地内共识别出2套成藏组合,其中白垩系成藏组合资源规模较大;预测了盆地内3类有利油气区,对于盆地下步勘探,提出应以白垩系成藏组合为主,并以前渊带和斜坡带为主要目标区带。For the problems that the overall exploration of Llanos basin is not systematic, hydrocarbon accumulation condition is not clear. In this paper, the tectonic evolution and tectonic division of this basin were studied, the hydrocarbon accumulation con-dition was summarized, and the characteristics of hydrocarbon accumulation were elucidated. Trap characteristics？ accumulation pattern and hydrocarbon distribution rules were deeply analyzed. Resource potential and exploration prospect were discussed and the next prospecting direction was pointed out. The results show that the Llanos basin mainly experiences three tectonic evolution stages including Craton marginal basin, Mesozoic arc back rift basin and Cenozoic foreland basin Several sets of hydrocarbon source rock and reservoir cap rock are developed in this basin Diverse Traps appear in the depression zone and slope zone with the northwest-southeast belt shape. There are two sets of accumulation consensus combinations, and resources in cretaceous is the largest. The advantageous exploration area is predicted. For the next step of basin exploration, Cretaceous accumulation set should be given priority, and depression zone and slope zone are the main target areas.
