| 摘 要： | 目前羌塘盆地的绝大部分烃源岩资料均来源于地表露头的分析数据,通过对羌资2井烃源岩和南羌塘坳陷扎仁地区地表烃源岩特征对比分析,从烃源岩岩性、有机质丰度、类型和成熟度等方面揭示了羌塘盆地的地表与地下烃源岩之间的差异。结果显示,羌资2井有机碳含量高于地表条件下的有机碳含量,有机质类型以Ⅱ1型干酪根为主,极少量为Ⅱ2型,而有机质演化程度也明显偏低。因此,认为羌塘盆地地下烃源岩具有非常好的生油能力,这对羌塘盆地烃源岩的评价有重要的现实意义。

| Abstract: | Most information about the source rocks in Qiangtang basin are originally taken from analytical data of the outcrops. This paper presents correlation and analysis of the characteristics of the source rocks in Qiangzi-2 well and on the surface in Zharen area in southern Qiangtang depression. And some differences of source rocks between them are revealed in lithology,organic matter's abundance,type and maturity,etc. The result shows that the content of organic carbon of Qiangzi-2 well is higher than that on t... |
