The major transporting layers for secondary migration are sand-beds of Es3, unconformable surface and fault. 油氣在烴源巖中的初次運移和在儲集層中的二次運移是油氣運移過程中連續而特點不同的兩個階段。
An effective method for solving a partial differential equation of secondary hydrocarbon migration is put forward. 本文給出了一種高效率求解油氣二次運移偏微分方程的方法。
The complicated fault-block reservoirs in Dongying Depression are the secondary trap deposits which had been migrated from deep to shallow after original reserves broken down. 東營凹陷的復雜斷塊油氣田是深層原生油氣藏被斷層破壞后，油氣經二次或多次運移至淺層的斷層伴生圈閉而形成的次生油氣藏。
