【摘要】：斋桑盆地位于"一带一路"重要的沿线国—哈萨克斯坦国东北部,二叠系成藏研究相对较少.基于斋桑盆地构造演化背景,通过与邻区准噶尔盆地西北缘在构造沉积演化、烃源岩、储盖组合以及运聚模式的对比,揭示其二叠系勘探潜力.结果表明:斋桑盆地和准噶尔盆地均为板块碰撞的产物,沉积体系受断裂控制;与风城组烃源岩类型相似,麦恰特组烃源岩有机质类型以Ⅰ和Ⅱ型为主,源岩发育于高盐度、强还原性水体环境,为一套好-很好的烃源岩;但斋桑盆地二叠系储层中孔低渗,物性相对较好,且二叠系内部发育大套地层圈闭,可形成规模地层油气藏.综合对比分析表明斋桑盆地二叠系具有良好的勘探潜力.
[Abstract]:The Jaissang Basin is located in the northeast of Kazakhstan, an important country along Belt and Road, and the study of Permian reservoir formation is relatively rare. Based on the tectonic evolution background of Jhasang Basin, the Permian exploration potential is revealed by comparing the tectonic sedimentary evolution, hydrocarbon source rock, reservoir cap assemblage and migration and accumulation model with the northwestern margin of Junggar Basin. The results show that both Jaissang basin and Junggar basin are the product of plate collision, and the sedimentary system is controlled by fault, and similar to the source rock types of Fengcheng formation, the organic matter types of the source rocks of the Macarte formation are mainly type 鈪，
