| 摘 要： | 以新区、新层系油气资源调查为目标,采用野外调查与室内综合研究相结合的工作方法,重新厘定了石炭系—二叠系地层接触关系;建立了伊宁盆地石炭纪—二叠纪层序地层格架;查明了伊宁盆地石炭纪为"一谷一链"的沉积格局,即整体为一东西向裂谷,北部发育近东西向岛链,二叠纪为一向西开口的近东西向的陆相裂陷盆地;在石炭系阿克沙克组和二叠系铁木里克组发现2套优质烃源岩层。

| Abstract: | For the purpose of petroleum resource surveying in new area and new formation, with the combined method of field survey and laboratory research, the contact relationship and sequence stratigraphic framework of Carboniferous-Permian strata were determined. Meanwhile, it was found that Yining Basin was characterized by “one rift and one chain” sedimentary framework in Carboniferous, which was east-west rift in general and east-west chain developed in northern area, however, it became a nearly east-west terrestrial rift basin with western opening direction in Permian. In addition, two sets of high quality source rocks were found in Akashake Formation of Carboniferous and Tiemulike Formation of Permian. |
