Abstract

For the question of BS11 surfactant's poor deliquescence into consideration, the hydrophilic structural of amphibious surfactant is changed and the new kind of hydroxyl sulphonate betaine surfactant BS13 is developed. We researched that the interfacial tension,IFT, between the sewage solution of the new kind of hydroxyl sulphonate betaine surfactant BS13 and dehydrated crude oil from a wellhead in central district Xing-5,daqing is investigated, and the influences of the interfacial tension in one surfactant BS13 system by joining a little sacrificial agent Na3PO4 and polymer is studied. As a result the BS13 itself creates ultralow IFT in low mass fraction. With small amount of sacrifice, the interfacial tension system is more stable and the curve is more smoothly; some more amount of polymer is joined, the time in a low interfacial tension is longer and the system have better capacity in increasing the efficiency of oil washing in process of oil displacement.
