摘　　要：对七个泉油田E23油层22个原油样品进行了常规柱色谱分离,应用含氮化合物参数并结合其砂体展布、断层分布的研究,对E32油层油气运移方向和油气充注点进行了分析.结果表明:油气运移方向为自背斜近南北两侧进入背斜的油气沿着背斜长轴向中部地区运移,而自6-30井进入背斜的油气分别向背斜南北两侧和东北侧运移,油气注入点为6-15井、中5井和6-30井.以断层和砂岩储集体为主要运移通道,形成以断鼻为主的构造油气藏类型是七个泉油田下干柴沟组主要的油气运聚模式.Through conventional chromatogram extraction of 22 oil samples,the migration and injection direction of oils are investigated by the nitrogen compounds combined with its sandbody and fault distribution in Qigequan oilfield.The oils migrated from south and north of anticline to the middle area.And the oils migrated from well 6-30 to the south and north,northeast of anticline.The injection spot is well 6-15,Zhong 5 and well 6-30.The accumulation model is that its migration pathway is faults and sand reservoir and the fault nose is its main hydrocarbon type.
