| 摘 要： | 本文对伊犁盆地伊宁凹陷中央隆起带的宁3井沉积岩颜色指数特征进行了分析,认为伊犁盆地从二叠纪至第四纪,其沉积环境明显经历了两个氧化—还原环境旋回,与盆地演化相对应;指出二叠系铁木里克组（P2t）和三叠系小泉沟群(T2-3xq)至侏罗系西山窑组（J2x）为两套还原环境中形成的烃源岩层,盆地中存在二叠系和三叠—侏罗系两套有利勘探层系。

| Abstract: | This paper has analyzed the characters of color index of sedimentary rock of Ning-3 in the Central High of Yining sag. From Permian to Quaternary two distinct oxidation-reduction cycles of sedimentary environment which are correspondent to basin evolution are recognized. There are two sets of hydrocarbon source rocks, i.e., the Timulik Formation of Permian and the Xiaoquangou Group of Triassic to Xishanyao Formation of Jurassic, which are formed under reducing environment; and two advantageous exploration layers, i.e., Permian and Triassic-Jurassic. |
