库木库里盆地为渐新世早期因阿尔金断裂与东昆中断裂交汇处的离散作用和阿尔喀山北缘的前陆坳陷作用而形成的新生代陆相拉分-前陆复合型盆地。本文从沉积地层的沉积相演变、烃源岩、构造与圈闭以及储盖条件等方面对盆地的石油地质条件进行了初步评价,已有的资料表明盆地构造与圈闭以及储盖条件良好,但烃源岩不佳。故认为盆地的油气勘探潜力将依赖于库木库里-梯子梁凹陷和河岔口-土房子凹陷烃源岩的发育情况与质量,并提出了勘探建议。
The basin of Chumukuri basin was formed in the Cenozoic continental rift-foreland compound basin formed by the discrepancy between the confluence of Altyn Tagh fault and East Kunquina fault in the Oligocene and the foreland depression in the northern margin of Arga. . In this paper, the geological conditions of the basin are preliminarily evaluated from sedimentary facies evolution of sedimentary facies, source rocks, structure and traps, and reservoir conditions. The existing data show that the basin has good tectonic and trapping conditions, However, the source rock is poor. Therefore, it is considered that the potential of oil and gas exploration in the basin will depend on the development and quality of source rocks in the Kuquli-Ladzile Sag and Hechukou-Tujia Sag, and some exploration suggestions are put forward.
