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
补充资料:泡沫驱
分子式:
CAS号:

性质:以泡沫作驱油剂的驱油法。泡沫由水、气、起泡剂组成。配泡沫用的水,可用淡水,也可用盐水。配泡沫用的气体,可用氮气、二氧化碳、天然气、炼厂气或烟道气。配泡沫用的起泡剂主要是表面活性剂。常用的起泡剂有烷基磺酸钠、烷基苯磺酸钠、聚氧乙烯基醇醚等。泡沫驱油剂黏度比水大,有气阻效应,起泡剂本身又是表面活性剂,故驱油效率比水高。泡沫驱油另一优点是降低了泵注费用。
