摘　　要：目的对海拉尔盆地贝西斜坡主要勘探目的层系进行层序、体系域划分及扇体的刻画。方法以层序地层学等理论为指导,以工作站LANDMARK,GEOPROBE地震岩性圈闭识别和储层预测等技术为手段。结果根据形态特征将贝西地区的坡折带类型划分为反向断阶型、断折型、坡折型和简单弯折型4种;反向断阶型有利于构造油气藏的形成,断折型和坡折型有利于构造-岩性油气藏的形成,简单弯折型有利于岩性油气藏的形成。结论贝西斜坡的中坡折带是油气勘探的重要领域。Aim To classify the sequences and their system domain for exploration targets in Beixi slope of Hailer Basin. Methods Guided by the theory of sequence stratigraphy and others, use the following techniques： LANDMARK work station, GEOPROBE lithological trap identification, reservoir predication and so on. Results The fan bodies have been described. Finally, the limitations of the whole area＇s sequences and system domain have been unified. With the help of broken belt theory and according to the characteristics of its performances, the types of broken belt have been divided. Conclusion There are certain differential influences on hydrocarbon reservoir formation and enrichment for the above different types： the type of inverted faulted and step-shaped broken belt is good for the formation and enrichment of structural petroleum reservoirs; faulted and broken type and slope broken type are beneficial for the generation of structural-lithological petroleum reservoirs; simple curved-broken type is desired by the development of lithological traps.
