摘　　要：针对江苏油田低渗特低渗储层特征,采用江苏油田现场原油作为实验用油,采用去离子水作为实验模拟水,通过室内岩心模拟驱油实验研究,评价了VES(黏弹性)表面活性剂洗油剂、纳米洗油剂1#以及纳米洗油剂2#三种渗吸洗油剂驱油性能。结果表明,三种渗吸洗油剂在低渗条件下具有良好的驱油性,采收率提高均高于6.99%,综合考虑多种因素,VES表面活性剂洗油剂驱油效果最佳,而纳米洗油剂1#在毛管渗吸排油阶段的驱油效果最好。According to the characteristics of low permeability and ultra-low permeability reservoirs in Jiangsu oilfield,the crude oil in Jiangsu oilfield was used as experimental oil,and deionized water was used as experimental simulated water.The oil displacement performance of three kinds of imbibition oil displacement agents,VES(viscoelastic)surfactant oil displacement agent,nano oil displacement agent 1#and nano oil displacement agent 2#,was evaluated by indoor core simulation oil displacement experiment.The results show that the three kinds of imbibition oil displacement agents have good oil displacement under low permeability conditions,and the recovery rate is higher than 6.99%.Considering various factors,VES surfactant oil displacement agent has the best oil displacement effect,while nano oil displacement agent 1#has the best oil displacement effect in the stage of capillary imbibition.
