Mirror symmetry of petroleum occurrences is due to multistage-accumulation and remigration. 油气地球化学特徵性相似性与成藏多期性及油气运移对称性密切相关。
Oil-gas pools or fields found in Persian Gulf basin possess obvious remigration processes known as a complex petroleum system. 在波斯湾盆地，油气藏（田）形成过程中有明显的再次运移过程，即有复式石油系统。
An Zuo-xiang who wrote many articles to demonstrate it.It is indicated that there existed this remigration in rift basin,foreland basin and kraton basin. 此外,在南海的珠江口盆地和莺琼盆地表现双源相向运移形成大油气田的现象,另有一番油气田形成的复杂研究景象。
Dynamic analysis of gas formation revealed that the resisting force for the capillary tubes in the Upper Paleozoic reservoir was so high that it prevented the remigration of gas. 含气范围内的同一气层连通性较差，气水分布受区域构造控制，局部明显存在边底水，也没有整体活塞式气驱水作用形成的区域性气水界面。
After the starting of hydrocarbon migration,sealing characteristics of developing fault changes actively and leads to strong remigration in the same period. 油气移聚期开始后，发育中的断层的封闭性将活跃地转化，引起强烈的再运移。
