摘　　要：选取国内外典型页岩油盆地,从烃源岩特征和储层特征方面与鄂尔多斯盆地安塞地区长7页岩油进行对比,为安塞区页岩油勘探开发提供理论指导。结果表明,鄂尔多斯盆地安塞区长7页岩油沉积构造稳定,与西西伯利亚盆地相似;烃源岩地球化学特征适中,相较于国内外大型页岩油盆地而言较差,且厚度小,储层特征差,不利于储层改造,但其埋深浅,利于勘探开发。总体而言,鄂尔多斯盆地安塞区长7页岩具有较大的资源潜力,但同时具有较高的开发难度,其相对较浅的埋深成为实现页岩油成功开发的最大的优势。Ansai area of Ordos basin is the key area of shale oil exploration and development in China.Thus,typical shale oil basins at home and abroad are selected to compare the Ansai area of Ordos basin in terms of hydrocarbon source rock characteristics and reservoir characteristics,so as to provide reference for Ansai area exploration and development.The results show that the sedimentary and structural stability of Ansai area in Ordos Basin is similar to that of West Siberia Basin;the geochemical characteristics of source rock are moderate,which is worse than that of large shale oil basins at home and abroad,and the thickness is small,but its advantages lie in shallow burial depth,which is conducive to exploration and development;the characteristics of reservoir are poor,which is not conducive to reservoir transformation.Generally,Chang 7 layer in Ordos Basin has great resource potential,but at the same time it has high development difficulty.Its relatively shallow burial depth has become the biggest advantage to realize the successful development of shale oil.
