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。
Based on the study of the dynamic forming conditions of reservoirs, reservoirs and covers, the sub-dynamic factors of hydrocarbon migration and reservoir type, distribution and influencing factors of Budat buried hill oil and gas reservoirs in the Suderte tectonic belt of the Hailaer Basin, The buried belt reservoirs of Budat group in the tectonic belt developed well, and the cover and lateral sheltering conditions were good, forming the ideal buried hill trap. The oil and gas generated in the Beixi Depression migrate longitudinally along the faults and migrate laterally along the unconformities such as channels, alternatingly, forming a stepped migration and finally accumulating in the buried hills. The migration of oil and gas mainly occurred at the end of deposition of Yimin Formation and the end of sediment deposition of Damoguaihe Formation. The types and distribution of reservoirs are related to a variety of factors such as the shape of the trap, the location of the reservoir, the strength of the weathering and denudation, the tectonic function and the erosion of water during the geological period.
