摘　　要：在洪浩尔舒特凹陷中次洼海北构造群的勘探实践中,运用精细构造解释、生油评价、沉积相划分、储层预测反演、油藏建模等先进的勘探技术和手段,对腾一段油藏的形成条件进行了综合分析。浩尔舒特凹陷中次洼海北构造群油气资源较丰富,腾一段为主要油源层;油气运移以不整合面为主,断层和裂缝为辅;主构造区发育物性较好的储层,在构造翼部可形成有利圈闭;油气与圈闭良好配置形成油藏,指明了今后的勘探方向。在海北洪37井区创新认识,首次引进滑塌扇理论,精细剖析洪37油藏,建立受台阶断层、火山岩台地等因素控制的滑塌扇储集群油气成藏模式。In the exploration practice of middle secondary flat of Haibei Structures,The forming condition of TengⅠMember of the oil reservoir is analyzed by fine structure elucidation,genetic evaluation,sedimentary facies division,the inversion methods of seismic reservoir prediction,reservoir model building of the advanced exploitation.The result shows that in Haibei Structure oil and gas resource is rich,and TengⅠ Member is main oil source zone;the unconformity surface is main oil and gas migration,fault and fracture are secondary;the reservoir in main structural area is good physical property,and the favorable traps are formed in the structural limb;the good matching condition of oil-gas and the traps forms the reservoir,the exploration targets in the future are determined.By means of the knowledge in Haibei Hong Wellblock 37,it introduces slump fan theory and Hong 37reservoir,the oil and gas reservoir forming mode is established about slump fan reservoir group which are controlled by the step fault,volcanic rock tableland elements.
