| 摘 要： | 传统的成藏期分析主要从生、储、盖、运、聚、保各项参数有效配置，根据构造演化史、圈闭形成史与烃源岩生排烃史作出推断，常用的 3个方法是根据油源岩的主生油期、圈闭形成期、油藏饱和压力分析油气藏形成期。近10年来成藏期分析是在构造发展史、埋藏史、热演化史、沉积成岩史 4个方面地质历史分析基础上，更多地依靠成藏化石记录的地球化学和岩石学分析结果，获得成藏期定量数据。评述了成藏期定量分析的理论与方法：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，并讨论了它们在叠合盆地成藏年代学分析中实际应用及存在问题。

| Abstract: | Traditional methods for timing of petroleum accumulation are based on analysis of generation, migration, accumulation, reservoir, seal, and preservation and those factors relationship and efficiency, according to the history of structure, trap, and hydrocarbon fluids generation and expulsion. The routine three approaches to define timing of petroleum accumulation are main phase of oil generation for source rocks, timing of trap formation, and analysis of saturation pressure for pool. The research works were more focused on the analysis of fossil records of petroleum migration and accumulation in the reservoirs in past ten years, besides routine geohistory analysis, in order to obtain the quantitative data to constrain the timing and duration of petroleum accumulation. This paper reviewed the theory, methods and trends of timing of petroleum accumulation, including the diagenesis sequence of reservoir rocks and hydrocarbon fluids emplacement events, isotopic dating of authigenic minerals, fluid inclusions, palaeomagnetism, and accurate analysis of hydrocarbon generation history. |
