| 摘 要： | 利用有机碳含量、镜质体反射率等手段,对松辽盆地北部上白垩统青山口组一段、嫩江组一段、嫩江组二段三个层位油页岩的分布、地球化学特征及富集条件进行研究表明:目标层主要以深湖相、半深湖相的黑色泥岩和页岩为主,厚10~30m不等;有机质丰度较高,TOC值介于1.873%~10.625%之间,平均6.47%,干酪跟类型以Ⅰ型、ⅡA型为主,成熟度Ro普遍为0.41~0.78,处于低成熟阶段;三个层位油页岩有机质来源以湖生生物及海侵带来的藻类等母源物质为主,沉积时期主体处于海侵深水、强缺氧环境,有机质保存条件较好。

| Abstract: | Determination of Organic carbon content, vitrinite reflectance of oil shale samples of to First Member of the Cretaceous Qingshankou Formation and First and Second Members of the Nenjiang Formation in the north of the Songliao Basin shows that they are deep and semi-deep lacustrine black mudstone with a thickness of 10-30 m and have higher abundance of organic matter with TOC values of 1.873 to 10.625%, an average of 6.47%, with kerogen of I and II A types, and a maturity of 0.41 to 0.78. The organic matter was derived from lake aquatic organisms and sea algae. |
