The further movement of the hydrocarbons into reservoir rock in a hydrocarbon trap or other area of accumulation is secondary migration.

烃类进一步运动进入储集岩石达到油气圈闭或其他聚集区是二次运移作用。

Passage systems of rift basins are linkage between source rock and trap, and unification between static factors and dynamic factors of forming reservoir.

断陷盆地输导体系是连接源岩和圈闭的纽带，是油气成藏静态要素和动态过程的统一体。

Due to far away from the hydrocarbon source rock, oil-gas migration and building-up conditions became the main controlling factor of the formation trap reservoir forming.

由于距离烃源岩较远，油气运移聚集条件成为地层圈闭成藏的主要控制因素。
