为什么大庆油田对水驱难以割舍?经过3年的示范引领,水驱精细挖潜示范区效果如何?在三次采油技术以及日益进步的油田开发技术面前,水驱这个相对“陈旧”的开采技术,在大庆还能走多远?在大庆油田53年的开发史中,水驱为油田开发立下汗马功劳。尽管聚合物驱和三元复合驱等三次采油已开展多年,并取得令人瞩目的成绩,尽管水驱产量逐年递减,但水驱从未退出过大庆油田开发的舞台,即使是现在,大庆油田的年产量仍有60%是通过水驱完成。
Why is it difficult for Daqing Oilfield to give up on water flooding? After 3 years of piloting, how well did the waterflood project tap the submarine? How can the waterflood be relatively “old” before the third oil recovery technology and the increasingly advanced oilfield development technology? How far can we go in Daqing? In the history of 53 years of Daqing oilfield development, waterflooding has made a lot of contribution to the development of oilfields. Although tertiary recovery such as polymer flooding and ASP flooding has been carried out for many years and remarkable achievements have been made, water flooding has never withdrawn from the stage of Daqing oilfield development even though waterflood production has been declining year by year. Even now, Daqing Oilfield 60% of annual production is still completed by water flooding.
