| 摘 要： | 研究区内已发现的超大型油页岩矿床位于吉黑地槽褶皱系松辽中断陷的一个三级构造单元--松辽盆地东南隆起内。研究区主要发育白垩纪地层，属于陆源碎屑岩沉积。经钻井岩心观察和采用“费舍尔”方法对含油率测试分析表明，油页岩层主要赋存在早白垩世青山口组和晚白垩世嫩江组。含油页岩层系整体为一套厚层的暗色泥页岩和油页岩组合。井间油页岩层对比和油页岩平面展布特征显示，该区油页岩呈层状、规模大、分布范围广、矿层稳定、连续性好。研究证实矿石含油率与有机质组分及总有机碳关系密切，矿石灰分大，属低品质油页岩矿石。通过对油页岩特征及成矿环境分析，认为矿床成因属于腐泥型页岩-油页岩。

| Abstract: | The oil shale deposit is located in the southeast uplift area of Songliao basin, and belongs to a third-class structural unit of Songliao central fault depression in the Jilin-Heilongjiang geosyncline fold system. The studied area was mainly filled with Mesozoic Cretaceous clastic rocks. On the basis of the core observation and "Fischer" oil content test classification, it is concluded that the oil shale developed in dark and brown-black mudstone layers, which mainly distributed in the Qingshankou Formation and the Nenjiang Formation of Cretaceous. The oil shale layers correlation among boreholes and the lateral distribution characteristics show that the oil shale is layered in a large scale, stable distribution, and better continuity. The bulk organic geochemistry data shows the oil yield of oil shale is closely related to organic matter type and total organic carbon content. Meanwhile, oil shale has high ash content, it is low quality oil shale ores. Combining the oil shale features and sedimentary environment, it is concluded that the origin of the oil shale was sapropelic oil shale. |
