| 摘 要： | 从油气成藏研究的发展阶段入手讨论了油气成藏期研究方法的演变,早期主要从生、储、盖、运、聚、保各项参数的有效配置,根据构造演化史、圈闭形成史与烃源岩生排烃史来推断油成藏期次和过程;近年来随着科技的进步,油气成藏期的"正演"分析方法,如对构造演化史、圈闭发育史与烃源岩生排烃史的研究越来越深入、精细,相应地深化了油气成藏条件、期次和过程的认识;同时,依靠"成藏化石"记录方面的成藏期定量数据分析可以"示踪"油气成藏期次和过程,如具有封闭特征的记录了沉积盆地早期油气成藏条件和过程的流体包裹体研究,具有开放特征的反映油气充注、演化过程的油气分异特征、储层沥青分析及自生矿物年代学研究等。并以克拉 2气田成藏过程为例,提出了在油气分异特征、包裹体分析、储层沥青分析和成岩矿物年代学等研究的基础上,结合盆地构造演化史、沉积埋藏史、烃源岩热演化史以及各种成藏条件的有效匹配,综合分析油气成藏期次、过程的方法。

| Abstract: | The method development of hydrocarbon filling periods is discussed at different study stages. At an early stage, hydrocarbon filling periods and process are derived according to the relationship and efficiency of generation, reservoir, seal, migration, accumulation and preservation. These methods, which are called "forward methods" based on the history of structural evolution, trap evolution and hydrocarbon generation and expulsion, have been developed in more details in recent years. At the same time, hydrocarbon filling periods and process can be "traced" based on fossil records of petroleum migration and accumulation in the reservoirs, such as differentiation of hydrocarbon, fluid inclusions, reservoir bitumen, isotopic dating of authigenic minerals. In the paper, the overall approach of hydrocarbon filling periods and process are displayed by elucidating the filling process of Kela-2, in the base of differentiation of hydrocarbon, fluid inclusions, reservoir bitumen and isotopic dating of authigenic minerals combined with the history of structural evolution, trap evolution, hydrocarbon generation and expulsion and the relationship and efficiency of every geological condition. |
