摘　　要：通过对海拉尔盆地苏德尔特构造带布达特群潜山油气藏生、储、盖静态成藏条件和油气运移期次动态因素及油藏类型、分布和影响因素的研究,认为苏德尔特构造带布达特群潜山储层发育,盖层及侧向遮挡条件良好,形成比较理想的潜山圈闭。贝西洼陷生成的油气沿断层纵向运移、沿不整合面等通道横向运移,交替进行,形成阶梯式运移,最后在潜山内聚集成藏。油气的运移主要发生在伊敏组沉积末期和大磨拐河组沉积末期。油藏的类型、分布与圈闭(储层)的形态、所处的位置、风化剥蚀作用强度、构造作用和地质时期水的溶蚀作用等多种因素有关。The analysis on the static conditions of reservoir forming including source rock,reservoir,cap rock,sideway guard conditions, and dynamic factors such as the phase of oil and gas migrating, reservoir design,hydrocarbon distribution and influencing factors reveal that the reservoir,cap rock and sideway guard condition of clastic buried hill reservoir in Sudeerte tectonic zone is favorable for ideal buried hill traps.The oil and gas formed in Beixi alternately migrated vertically along fault and laterally along unconformable surface to form step migration,and finally accumulating in buried hill traps.It is considered that there are two main oil/ gas migration periods:the end periods of Yimin and Damoguaihe sedimentation.The types and distribution rule of reservoirs are mainly controlled by the trap configuration,which is related to many factors such as location,weathering and erosion intensity, tectonic action,and water denudation and so on.
