| 摘 要： | 基于对鄂尔多斯盆地南部(镇泾—彬长—旬宜—富县地区)延长组不同层段暗色泥岩、碳质泥岩及油页岩样品的地球化学和测井资料的对比分析,研究了油页岩的识别标志及其分布规律。结果表明,不同岩性样品的生物标志物、生烃潜力及测井电性特征差异明显,油页岩具有典型的地球化学和地球物理综合识别标志,分布受沉积环境的控制作用显著,靠近湖盆中央的深湖—半深湖相带是油页岩的主要发育区。

| Abstract: | Based on the geochemical features and logging data of dark mudstone, carbonate mudstone and oil shale samples from different layers of the Yanchang Formation in the southern Ordos Basin (including Zhengjing, Binchang, Xunyi and Fuxian areas), the identification markers and distribution characteristics of oil shale have been investigated. The result shows that there are significant differences in biomarker characteristics, hydrocarbon generation potential and logging electrical characteristics. Oil shale has typical geochemical and geophysical composite identification marks. The distribution of oil shale is significantly controlled by sedimentary environment. Deep or semi-deep lacustrine facies which is near to the center of lake basin is the main development zone for oil shale. |
