摘　　要：传统的成藏期分析方法是通过盆地的构造发育史、圈闭形成史、烃源岩生排烃史的研究根据油源岩的主生油期、圈闭形成期、油藏饱和压力来分析油气藏形成期,属于间接确定油气的成藏期的方法。近些年来随着地球化学科学和有机岩石学的发展,各种依靠成藏化石记录的地球化学和岩石学分析方法应用到油气成藏期研究中,提供了油气成藏期研究的多种手段,主要包括:储层成岩作用与烃类流体充注序次、自生矿物同位素地质年代学、流体包裹体、储层磁性矿物古地磁学、生烃期精确分析等,并讨论了这些方法目前实际应用和存在问题。Traditional methods for petroleum accumulation timing are based on research of structural history, trap evolution, and hydrocarbon generation and expulsion and analysis of oil generation for source rocks, timing of trap formation, and reservoir saturation pressure, which is indirect methods. Recently, with development of geochemistry and organic petrology, various methods based on fossil records are applied in research of timing of petroleum, which provided many measures including: reservoir diagenesis and hydrocarbon fluids emplacement events,authi-genic mineral isotope geochronology, fluid inclusions,reservoir magnetic mineral paleo magnetism, and accurate analysis of hydrocarbon generation history. This paper also discussed the actual application and existing problem of these methods.
