通过对克百地区测井、试油资料的分析,总结了二叠系油气的分布特征,结合构造、沉积发育特征,分析了二叠系油气分布的控制因素.二叠系油气主要分布在佳木河组和上乌尔禾组,平面上油气主要沿地层尖灭线和断层分布,往凹陷中心,油气分布减少.油气藏类型丰富,主要有地层油气藏、断层油气藏、岩性油气藏以及复合油气藏.二叠系油气的分布主要受不整合、断层及岩相展布的控制,由于各控制因素在各层位油气分布中所发挥的作用不同,各层位油气分布也各具特点.“,”The Ke-Bai area is located in the western uplift of the Ke-Bai fault belt of the Junggar Basin.Logging and oil production data of the Permian oil-gas reservoir are summarized in this paper.Combined with structural and sedimentary characteristics,the distribution pattern and controlling factors of the Permian oil-gas accumulations were discussed.The Permian oil and gas mainly occur in the Jiamuhe Formation and upper Wuerhe Formation,and are mainly distributed along the pinch out lines and faults of the oil-bearing Formations in a plane view,and gradually decrease towards the center of the depression.There are many types of reservoirs,such as stratigraphic,fault,lithologic and complex ones.The distribution of the Permian oil-gas depends mainly upon unconformities,faults and lithofacies distribution patterns.The controlling factors are assembled in different patterns and each of the factors plays different roles.In this regard,the oil-gas distribution varies in different Formation.
