| 摘 要： | 随着我国低渗透油田步入三次采油阶段,三次采油用表面活性剂的研究成为当前研究的重点。ZC油田长2储层是典型的低渗透储层,本次为其选取了AESO3表面活性剂,其抗盐性与表面张力均符合长2储层流体的要求,本次选用的表面活性剂可以将储层驱油效率平均提高5.7%,将储层水相渗透率平均提高10%。

| Abstract: | As China's low permeable oilfield enters EOR stage,research on surfactants applied in EOR has become a key point at present.ZC oilfield long 2 reservoir is a typical low permeability reservoir,AESO3 surfactant was selected because its salt resistance and surface tension conform to the long 2 reservoir fluid requirements,application of the surfactant can averagely increase reservoir oil displacement efficiency by 5.7% and reservoir water phase permeability by 10%. |
