摘要： 泥页岩层系储集层的性质是决定页岩油藏存在与否的关键因素之一。以松辽盆地北部白垩系青山口组一段泥页岩层系为例，对其烃源岩地球化学特征、矿物含量以及储集空间特征等开展了研究，结果表明：青一段泥页岩层系有机质丰度较高（有机碳含量大都在1%~3%），干酪根类型以Ⅰ型和Ⅱ1型为主，且大部分泥页岩层系正处于生油高峰阶段；脆性矿物含量适中，发育大量不同类型的孔隙，为排烃提供了有效的通道，也为残留在泥页岩层系中的油气提供了充足的储集空间。青一段泥页岩层系整体含油性较好，估算页岩油资源量为78.37×108~97.97×108 t

Abstract: The reservoir quality is one of key factors for judgment of existence of the shale reservoir. Taking the Qing-1 member shale of Cretaceous Qingshankou formation in Songliao basin as an example, its geochemical characteristics of source rocks, mineral content and reservoir space characteristics were studied. The results indicate that the shale of this member is characterized by high abundance of organic matter with TOC of 1%-3%, I and II1 types of kerogen, at the peak stage of oil generation, moderate content of brittle minerals, and large number of different types of pores, which not only provide effective channels for hydrocarbon expulsion, but also offer sufficient spaces for the residual oil and gas in the shale. The Qing-1 member shale has a high oil potential on the whole, and the estimated shale oil resource amounts to 78.37×108~97.97×108 t
