摘要
成藏动力系统又可称为成藏系统或运聚系统,是指含油气系统内一个相对独立的、自然的油气运移—聚集系统,它与相邻成藏动力系统之间存在着不同的油气成藏条件、成藏动力以及不同的成藏特征。成藏动力系统在盆地中的位置介于含油气系统与区带之间。成藏动力系统与含油气系统的区别在于:含油气系统的核心是“源”,同一含油气系统具有共同的烃源灶,它与其他含油气系统以烃源灶的不同相区别;而成藏动力系统则强调的是系统内油气运移和聚集成藏特征的共同性或相似性,同一成藏动力系统各油气藏具有相近的成藏条件、成藏动力、相似的运聚机制和相似的成藏模式。
Petroleum reservoir-forming dynamic system which is also refered to petroleum reservoir-forming system, or migration-accumulation system, is a relatively independent natural migration-accumulation system within a petroleum system. It is distinguished from its neighboring counterparts in reservoir-forming condition, dynamics and migration and accumulation characteristics. The status of petroleum reservoir-forming dynamic system in a petroliferous basin is just between a petroleum system and a play. It should be noted that a petroleum system can not only include two or more petroleum reservoir-forming dynamic system, but one system as well. The petroleum reservoir-forming dynamic system is different from petroleum system in that source kitchen is most important to the latter, in which different accumulations share the same hydrocarbon-generation kitchen, whereas migration and accumulation are most important to the former, which is characterized by the same or similar migration-accumulation conditions, dynamics, mechanisms and models.
