In case of a condensing gas drive, the original reservoir fluid and the injection gas are not miscible, but miscibility may be achieved at a later time, at the injection well. 如果進(jìn)行凝析氣驅?zhuān)⑷刖械脑家后w與注入氣在起初是不可能混相的,但過(guò)一定時(shí)間混相則可能發(fā)生。
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. 含氣范圍內的同一氣層連通性較差,氣水分布受區域構造控制,局部明顯存在邊底水,也沒(méi)有整體活塞式氣驅水作用形成的區域性氣水界面。
