摘　　要：为清晰认识准噶尔盆地阜东斜坡区侏罗系齐古组油气富集条件,为新疆油田公司油气勘探开发提供可靠保证,利用钻测井、地震等宏观资料和薄片、X衍射及扫描电镜等微观资料,对齐古组油气成藏条件(烃源岩特征、储层特征、疏导体系特征及异常压力特征)进行了分析。结果表明:(1)齐古组油气藏的油源包括二叠系和侏罗系烃源岩,以侏罗系为主;(2)齐古组一段储集砂体主要为水下分流河道砂体,齐古组二段和齐古组三段储集砂体以分流河道砂体为主,沉积环境、异常压力以及储层中凝灰质成分体积分数是优质储集砂体的控制因素;(3)齐古组油气疏导格架由沟通油源断裂和疏导层共同组成;(4)齐古组主要发育构造-岩性油气藏,局部发育岩性油气藏,勘探潜力巨大。In order to clearly understand the petroleum accumulation factors of Qigu formation in the Fudong slope area of the Junggar basin and to provide reliable guarantees for oil and gas exploration and development of Xinjiang Oilfield Company,macroscopic data such as drilling wells and earthquakes,and microdata such as thin sheets,X diffraction and scanning electron microscopy were used to analyze the petroleum accumulation conditions(hydrocarbon source rock characteristics,reservoir characteristics,dredging system characteristics and abnormal pressure characteristics)in Qigu formation.Conclusions were drawn as follows:(1)The oil sources of the Qigu formation reservoirs included the Permian and Jurassic hydrocarbon source rocks,mainly Jurassic.(2)Reservoir sands in first member of Qigu formation were mainly underwater distributary channel sands,and in second and third member of Qigu formation,were mainly distributary channel sands.Sedimentary environment,abnormal pressure and volume fraction of tuffaceous component were controlling factors of high quality reservoir sands.(3)The Qigu formation hydrocarbon dredging grid were composed of conncted oil source fracture and dredging layer.(4)The Qigu formation mainly developed tectonic-lithologic reservoirs and locally developed lithologic reservoirs,which had great exploration potential.
