| 摘 要： | 本文从沉积演化的角度分析了羌塘盆地中西部“冈玛错－西雅尔岗”隆起的演化过程，隆起在晚二叠世处于雏型发育阶段，晚三叠世肖茶卡－中株罗世雀昏时期为定型阶段，白垩纪－新生代为变形改造阶段。每一阶段隆起都控制着不同形式的生储盖组合的发育。隆起周缘具半地堑结构的凹陷是良好的油气聚集带之一。近隆起带北侧的构造层变形强度不大，对油气的后期保存比较有利。 |

| Abstract: | The evolution of the Gangmar Co-Xiyerkang Dome in the central and western parts of the Qiangtang Basin is analyzed in sedimentary aspects. The dome was primary in the Late Permian, completely developed the Late Triassic-Middle Jurassic and deformed in the Cretaceous-Cenozoic period. Different source-reservoir-cover types developed in the three stages. The half-graben around the dome was better place for oil-gas migration. The strata adjacent to north of the dome were strongly deformed and this was benefit for the preservation of oil and gas. |
| Keywords: | Qiangtang basin dome rift half-graben oil gas Xizang(Tibet) |
