| 摘 要： | 北羌塘盆地发育的布曲组海相碳酸盐岩是重要的烃源岩之一，但是由于研究程度低，一些油气地球化学问题尚不清楚。应用生物标志物分析技术，结合其它地球化学资料，对北羌塘盆地侏罗系布曲组烃源岩进行了有机质生源构成、沉积环境、成熟度进行了讨论。研究结果表明，该烃源岩的发育环境为海相还原环境，有机质母质主要为低等水生生物，有高等植物的混入，处于高成熟阶段，具备油气生成的有力条件。

| Abstract: | It is the one of the most important source rocks for the Buqu marine carbonate rocks in North Qiangtang Basin,but some issues about oil and gas geochemistry are not clear because the lowly research.The biologic-source constitution,sedimentary environment and maturity of organic matter in the Jurassic carbonate rocks in North Qiangtang Basin is studied preliminarily by means of biomarker analysis technology combined with other geochemical data.The result reveals that the hydrocarbon source rock were developed in sedimentary environment,the organic source material is mainly low-grade hydrobios mixed with high-grade plants.The source rocks have higher maturity,and possess favorable conditions to form gas and oil. |
