| 摘要: |
| 吐哈盆地三叠系油气资源丰富,勘探潜力巨大,但目前对该盆地的油气成藏与分布的主控因素尚存争议。本文应用成藏分析理论,从盆地整体出发,探讨油气藏形成与分布的主控因素。认为油气具有多期成藏、晚期调整的特征,成藏期主要决定于构造运动期次、圈闭发育与时空配置,以及断层活动时期等因素;油气藏的分布主要受前陆盆地的性质控制,盆地的不同区带、不同构造段和不同层位,其主控因素存在明显差异。 |

| Abstract: |
| The Turpan-Hami Basin abounds in hydrocarbon resources and has great petroleum potential.The controlling factors for the Triassic hydrocarbon distribution are dealt with on the basis of the analysis of reservoir formation in the Taibei depression,Turpan-Hami Basin,including tectonic setting,geological structure,fault,unconformity,source-reservoir-seal association and trap arrangement,and fluid dynamics.The hydrocarbon accumulation has gone through multiple stages,and evolved in the later stages.The hydrocarbon accumulation stages depend upon the stages of tectonism and faulting,trap development and tempo-spatial arrangement,The hydrocarbon distribution,which varies in distinct regions and structural positions of the basin,is mainly governed by the attributes and features of the foreland basin. |
