摘要
伊宁复合盆地成生发展可划分为石炭纪一早二叠世、晚二叠世和新生代３个构造发展阶段，相应地先后形成了孤内盆地、孤内残余盆地和远源碰撞山间盆地３种性质各异的原型盆地。弧内盆地属典型拉张型盆地，弧内残余盆地属地幔冷却收缩沉降盆地，生油岩系均较发育；远源碰撞山间盆地属压性盆地，生油岩系不发育。前两类盆地油气前景较好。
Abstract Three stages of tectonic evolution for Yining composite basin are distinguished: Carboniferous early Permian, late Permian and Meso-Cenozoic, correspondingly three prototype basins, i. e. an intra-arc basin, an intra-arc remnant basin and intermontane basin dynamically dominated by distal collision were successively formed. The intra-arc basin is a typical extensional basin, and the intra-arc residual basin is attributed to a depressed basin resulted from the cooling shrinkage of the mantle, both with developed source rock series.The distal-collisional intermontane basin is a compressive basin, with poor developed source rocks. Therefore the former two basins have a promising prospect for oil-gas exploration
