摘　　要：阿拉伊盆地具有较大的勘探潜力,烃源岩为古近系、白垩系和中-下侏罗统的海相与湖相泥岩、灰岩和泥灰岩。主要油气储集层为滨浅海相和三角洲相的砂岩和碳酸盐岩,泥岩和膏岩为盖层。油气圈闭主要有构造型、构造-地层复合型和地层型等3种。中央背斜带是近期的重点勘探区带。Play Basin is of considerable exploration potential, and the main hydrocarbon source rocks are Paleogene black shale, Cretaceous limestone and the coal-bearing of lower-middle Jurassic, the chief reservoir beds are the marine and delta sandstones and carbonate rocks., the regional cap rocks are shale and gypsolyte from the upper Jurassic to the Pliocene. The traps are classified into three types： the tectonic, the tecto stratigraphic and the stratal traps. At present, the central anticline belt is the major short-term exploration area.
