常规驱油剂的筛选是通过界面张力仪或是岩心驱替的方法评价,这些方法测量,能够定量评价出较好的驱油剂,但不适于大量驱油剂的筛选。在静态脱油试验的基础上,提出了一种新型的筛选驱油剂方法。该方法是将改装后的吸水仪应用在驱油剂的静态脱油试验中。通过测量出吸水仪上不同驱油剂或是相同驱油剂不同浓度的驱油量,来快速评价出驱油剂的驱油效果。该方法操作简单,数据的可靠性强,建议推广使用。
驱油剂提高采收率的机理是扩大波及系数和提高洗油效率,不同种类的驱油剂提高采收率的机理不同,有的主要是通过增粘性扩大波及系数,而有的主要是通过降低油水界面张力、改变储层岩石的润湿性来提高洗油效率的。对不同种类驱油剂性能的室内评价方法不同,对增粘性驱油剂性能的
