| 摘 要： | 辽河双南油田的原油大多属于正常比重的原油,其生物标志物分布与组成上呈现出姥鲛烷、植烷和甾烷的C27R和C29R均势,而重排藿烷、新藿烷和伽马蜡烷具有含量较低的特征。这种均势和特征表明原油来源于淡水环境条件下形成的混合型有机质。甾萜烷和芳烃成熟度参数表明部分原油属于成熟原油,如双201等井的原油;另有部分原油则属于未成熟原油,如清5井和锦135井原油。不同成熟度的原油具有明显不同的轻烃组成,油源对比结果表明这些原油主要来源于该地区的沙三段烃源岩。

| Abstract: | The crude oils from Shuangnan oilfield, Liaohe basin are unbiodegraded oils with normal density. In the distributions and compositions of biomarkers, the ratios of pristine to phytane, and sterane C-{27}20R to C-{29}20R are about 1.0, and the abundances of C-{30} diahopane, C-{29} neohopane and garmmacerane are relatively lower, showing that they are derived from the source rocks with Ⅱ kerogen deposited under fresh water lacustrine environment. Based on the molecular maturity parameters such as... |
