摘要： 酒泉盆地青西凹陷和营尔凹陷是两个富油凹陷,具有较大的勘探潜力。综合分析两个凹陷的石油地质条件后认为,它们既有相似之处,又有明显的区别。二者皆为早白垩世断陷,但后期改造及变形有明显差异。由于凹陷油气成藏在晚期,因此,对于油气勘探而言,两个凹陷在新生代时期的差异和区别就决定了它们的勘探领域和目标类型有所区别,从而决定了勘探思路与部署有所不同。

Abstract: Qingxi sag and Ying'er sag are the two oil-enriched sags in Jiuquan basin with large potentials for exploration. Composite geological condition analysis shows they are of similarity and obvious differences, characterized by same Early Cretaceous fault depression, same hydrocarbon accumulation in late period and different modifications and deformations in Cenozoic, which determine their explorative domains and targets along with their thoughts and deployments for exploration should be somewhat different.

Key words: Jiuquan basin, Qingxi sag, Ying'er sag, Resources size, reservoir condition, explorative thought
