摘要: 银根-额济纳旗盆地是一个油气勘探程度很低的含油气大型盆地。它是在前寒武纪结晶陆块与古生代褶皱双重基底上发育起来的中、新生代沉积盆地,经历了侏罗纪扭张和白垩纪伸展2个主要演化阶段,发育断陷和裂谷两种类型;以众多的相互分隔的小型沉积凹陷为主要特征。存有中 -下侏罗统、下白垩统巴音戈壁组及苏红图组 3套含油气系统,每个生烃凹陷构成独立的含油气系统。从油气地质条件来看,具有良好的勘探前景。

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
