Synergism of Alkylbenzene Sulfonates in Enhanced Oil Recovery
Abstract:
The raw heavy alkylbenzenes were fractionately separated into different fractions, from which five fractions with low, middle and high average molecular weight were collected and sulfonted by ClSO3H into corresponding heavy alkylbenzene sulfonates(HABS). Their synergetic effects on the interfacial tensions of Sichang(Daqing Oilfield) oil-water have been investigated. The interfacial activity of the mixed HABS of different molecular weight has been remarkably improved in comparison with that of single HABS.
