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
