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(guò)程中連續而特點(diǎn)不同的兩個(gè)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(yíng)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(jīng)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。
