【摘要】：松辽盆地油页岩资源极为丰富,本次研究利用位于松辽盆地北部的全取芯井,对油页岩有机质峰度、有机质类型、有机质成熟度和工业品质进行了研究,并分析了研究区油页岩的沉积环境。研究结果表明:松辽盆地北部青山口组一段共发育8层油页岩,平均含油率为5.26%,最高含油率可达12.65%,油页岩有机质峰度较高,有机质类型主要为Ⅰ型和Ⅱ型,处于未成熟-低成熟的热演化阶段。工业品质研究表明,油页岩主要为中等偏高品质、高灰分、较高挥发分、高发热量、低密度和特低硫型。通过对沉积环境的分析,研究区油页岩主要形成于半深湖-深湖,其中品质较好的油页岩层发育在高水位体系域中,因为较深的湖泊水体可能有助于油页岩中有机质的保存。
[Abstract]:The oil shale resources in Songliao Basin are extremely rich. In this study, the kurtosis, type, maturity and industrial quality of organic matter in oil shale were studied by using the core well located in the northern part of Songliao Basin. The sedimentary environment of oil shale in the study area was analyzed. The results show that there are 8 layers of oil shale in the first member of Qingshankou formation in the northern part of Songliao Basin. The average oil content is 5.26 and the highest oil content can reach 12.65. The kurtosis of organic matter in oil shale is relatively high, and the types of organic matter are mainly type 鈪，
