摘　　要：重点从鄂尔多斯盆地陇东地区长7段油页岩的地质、地化与含油性等方面分析了其页岩油的地质特征,粗略估算了长7段页岩油的资源潜力。油页岩主要分布在长7段中下部,横向连续性好。有机质丰度高,有机质类型以Ⅰ、Ⅱ型为主,并处于成熟演化阶段,以生油为主,具有较好的含油性。采用体积法对鄂尔多斯盆地陇东地区长7段页岩油的潜在资源量进行了估算,约为283.2亿t,勘探潜力较大,资源丰度为56.64×104 t/km2,是研究区潜在的重要非常规石油资源。By analysis of the geological and geochemical aspects and oiliness of oil shale in the Layer 7 of Yanchang Formation in Longdong Area, （）rdos Basin, the authors analyzed the geologic features of shale oil and calculated the resource potential of shale oil in this area. Oil shale is mainly developed in the middle and lower part of the Layer 7 of Yanchang Formation with good lateral continuity. The oil shale is abundant in organic matter of type I ]I ~ The organic matter is in maturation evolution stage and mainly generates oil, and thus it has high oiliness. Using the volumetric method, the resource of shale oil in the Layer 7 o{ Yanchang Formation is about 283.2 ×10^8t/km2 and oil resource abundance is 56.64 ×10^4t/km2. The research indicated that the shale oil of the Layer 7 of Yanchang Formation in Ordos Basin has high exploration potential, and the shale oil is important unconventional oil resource in this area.
