Abstract: Yinggen FEjinaqi basin is a large hydrocarbon basin with very low exploratory degree. The basin is a Mesozoic and Cenozoic sedimentary basin developed on dual basement, Paleozoic fold basement and Precambrian crystalline land block, and underwent Cretaceous expanding and Jurassic transtensional evolution stages, with developed fault depressions and rifts. It is mainly characterized by many isolated and small depositional sags. There exist three petroleum systems of Middle and Lower Jurassic and Cretaceous. Each hydrocarbon source sag forms independent petroleum system. Geologically, this basin has good prospect for petroleum exploration.

Key words: Yinggen-Ejinaqi basin, petroleum system, Oil and gas exploration
