4)  foam flood
泡沫驱
1.
The CO2 gas flood pilot project performed at Caoshe oil field,North Jiangsu,was uneffective and a CO2 foam flood project is adopted instead.
苏北草舍水驱油田CO2气驱先导试验效果不佳,转而采用CO2泡沫驱。
5)  foam flooding
泡沫驱
1.
Optimized design of parameters of enhanced foam flooding in west block of Chengdong oilfield;
埕东油田西区强化泡沫驱参数优化设计
2.
Technology of enhanced foam flooding was studied for the purpose of enhancing oil recovery in oil reservoirs with strong heterogeneity and big channel.
针对强非均质油藏和大孔道油藏提高采收率的需要,开展了强化泡沫驱油技术研究。
3.
The result shows that oil recovery was increase by 20 percent after using DP - 4 foaming agent and the single foam flooding was not efficient under higher residual oil content .
结果表明,DP-4复合泡沫驱可提高采收率20%以上,在残余油含量较高时,单一DP-4泡沫驱油效果差,但在高渗模型没有残余油的情况下,DP-4泡沫剂使高、低渗模型产液量完全反转,低渗模型采收率提高。
6)  foam flood
泡沫驱油

性质:在三次采油过程中,使用化学方法,即注入表面活性剂-聚合物或碱性水和聚合物,以降低界面张力,从而降低束缚残余油的毛细管力,以及保持有利的水-油的流度比,达到有效地驱替集油带,提高采油的收率。为了节省加入的化学品,可将注入化学品和注水交替进行,这就称为段塞。所加入的化学品称为段塞驱油剂。
