| 摘 要： | 本文从沉积、地球化学的角度分析了羌塘盆地的油气生成特征.羌塘盆地的沉积及古地理环境控制了多层系生油岩的形成,但主要为三叠系和侏罗系以海相沉积为主的碳酸盐烃源岩和泥质烃源岩,厚度巨大,有机质丰度高,热演化程度较高,生烃潜力大,构成了羌塘盆地主力烃源岩.综合分析认为盆地南北坳陷连接处的鞍部为含油气远景最有利区.

| Abstract: | From the view of sedimentary and geochemistry, the characteristics of hydrocarbon generation in the Qiangtang Basin have been analyzed. In the Qiangtang Basin, the environment of deposit and paleogeography controlled the formation of multilayered source rocks, which developed mainly in Triassic and Jurassic. The marine carbonate and mud source rocks are characterized by large thickness, abundant organic matter, huge hydrocarbon generating potential, so as to become main source rocks in the basin. Based on the comprehensive analysis of petroleum geology, the authors represented that the central parts of Qiangtang Basin should be the favorable exploration region. |
