摘　　要：本文以松辽盆地东南隆起区吉扶地3井为研究对象,通过岩心观察、样品测试等手段对上白垩统青山口组1段油页岩进行评价。研究分析表明:JFD3井油页岩主要赋存于青山口组一段下部,共有2个矿层,(1)号矿层厚度5.50 m,平均含油率4.5%,最高含油率为6.2%。(2)号矿层厚度4.80 m,平均含油率5.50%,最高含油率为15.90%。青山口组(1)、(2)号矿层为原位开采的首选层位;属于特低硫—低硫油页岩,油页岩岩段主要由含油率与小体积质量和灰分及挥发分显示一定的负相关性,以及总有机碳含量的TOC呈明显的正相关性,这可作为油页岩质量的评价替代指标。In this paper, the authors taking the Well JFD3 in the southeast uplift of SongLiao Basin as the research object, and evaluate the oil shale of the first member of Qingshankou Formation of Upper Cretaceous by means of core observation and sample test. The research and analysis show that the oil shale of Well JFD3 mainly occurs in the lower part of the first member of Qingshankou Formation, with a total of two ore beds. The thickness of No.1 ore bed is 5.50 m, the average oil content is 4.5%, and the maximum oil content is 6.2%. The thickness of No.2 seam is 4.80 m, the average oil content is 5.50%, and the maximum oil content is 15.90%. No.1 and No.2 ore beds of Qingshankou Formation are the preferred horizon for in-situ mining;it belongs to ultra-low sulfur low sulfur oil shale. The oil content of oil shale section shows a certain negative correlation with small volume mass, ash and volatile matter, and an obvious positive correlation with total organic carbon content(TOC), which can be used as an alternative indicator to evaluate the quality of oil shale.
