摘要: 准噶尔盆地莫索湾凸起属于典型的凹中凸构造单元,有优越的烃源条件,包括石炭系、二叠系、侏罗系三套主力生油层系;垂向上主要发育四套储盖组合。莫索湾凸起的构造沉积演化与地质结构决定了其油气聚集的主要特点,先后经历了早期成藏与调整和中晚期的成藏与再调整,具有“两期成藏、两期调整”特征。生油期、运移期、成藏期、调整期在时空上的有利配置,使本区成为多层系油气富集的有利地区。

Abstract: Mosuowan Uplift in Junggar Basin is a typical uplift structural unit in the depression with the superior conditions for hydrocarbon source. It has three sets of main hydrocarbon source series - Carboniferous, Permian and Jurassic. Vertically, there are four sets reservoircap assemblages developed in the structure. The structural and sedimentary evolution and geological structure of Mosuowan Uplift determines the main characteristics of its oil and gas accumulation. It has experienced accumulation and adjustment in the early period and accumulation and re-adjustment in the middle and late period, characterized with "two-stage accumulation and two-stage adjustment." The favorable allocation of sourcing stage, migration stage, accumulation stage and adjustment stage in space makes this region a favorable oil and gas abundance region with multiple intervals.
