摘　　要：基于前人对富林洼陷F117-F121井区的精细构造解释、油源分析,创新性地提出本区中生界油藏类型为下排式;采用流体包裹体压力恢复方法,并结合岩心、岩石薄片观察,分别从源岩超压和裂缝输导体系两方面论证,证实了研究区油气成藏类型确为下排式;采用数学公式演绎法,引入"压降"概念,量化评价下排式油气运聚最大波及范围为172.84m,该结果与实际试油成果排烃范围为180m吻合。Based on the study of structures and oil sources in the F117 Well Area of the Fulin Sag made by the previous researchers,downward petroleum migration in the Mesozoic of this area was proposed for the first time in this paper.Through recovery of the pressure using fluid inclusions,combined with the observation of rock thin sections and core,the downward migration of oil and gas is proved from two aspects respectively,i.e.the overpressure and crack passage system.Using mathematical deduction as the method,introducing the concept of＂pressure drop＂,the maximum downwards transportation of oil and gas may reach the range of 172.84 m,fit with the figure of 180 mfrom oil production test.
