摘　　要：吉林省松辽盆地是我国重要的油页岩成矿区。油页岩层位主要赋存于白垩系的青山口组和嫩江组中。油页岩主要分布于青山口组一段和嫩江组一、二段地层中。温湿的气候条件、大量的藻类和浮游动植物,以及介形虫、植物等为油页岩的形成提供了有机物源。对松原地区油页岩的45个岩芯样品进行分析。嫩二段TOC平均值约为7.00%,高于嫩一段的5.80%。嫩一段的含油率平均值高于含油率为4.60%的嫩二段。青一段油页岩的TOC平均值为7.60%,含油率平均值为5.10%。Songliao basin is the most important oil shale mineralization area in China.The oil shale layer mainly occurs in the Qingshankou Formation and Nenjiang formation of Cretaceous period.Oil shale is mainly distributed in the 1st section of Qingshankou formation as well as 1st and 2nd section of Nenjiang formation.The suitable environmental of warm and humid climate,agreat amount of algae,and plankton,ostracods,and some other plants provide organic resources for the formation of oil shale.Through the analysis to 45 oil shale samples in Songyuan area,the results show that the average TOC value in the 2nd section of Nenjiang formation is about 7.00%,which is higher than 5.80% of 1st section in Nenjiang formation.The average value of oil-containing rate in 1st section of Nenjiang formation is higher than the 2nd section which is about 4.60%.The average TOC value of 1st section of Qingshankou formation is 7.60%,and average oil-containing value is 5.10%.
