摘　　要：低渗透油藏具有一定的特殊性,渗透率低,注水开发效果不佳,开发难度较大,近年来,有人提出了在开发过程中加入表面活性剂,用这种方法来提高低渗透油藏的采收率。纳米表面活性剂与普通表面活性剂进行比较可以发现,纳米表面活性剂的粒径普遍较小,降低界面张力的能力较强,对于提高采收率有很大的作用。对实验室自制的HY纳米表面活性剂和SDS表面活性剂从粒径、界面张力、耐温性能、抗盐性能和驱油效果5个方面进行对比实验,最后分析得出HY纳米表面活性剂针对低渗透油藏的洗油效果更好。Low permeability reservoir has certain particularity,its reservoir physical property is poor and the percolation mechanism is complex,which leads to its difficult development,and in recent years,the recovery rate is low,the development effect is not good,adding surfactant in the development process is an effective method to improve the recovery rate of low permeability reservoir.Compared with ordinary surfactants,nano surfactants have smaller particle size and stronger ability to reduce interfacial tension,which plays a great role in enhancing oil recovery.In this article,a comparative experiment was carried out on the laboratory-made HY nanosurfactant and SDS surfactant in terms of particle size,interfacial tension,temperature resistance,salt resistance and oil displacement effect.Finally,the analysis showed that HY nano-surfactant had better oil washing effect on low permeability reservoirs.
