Abstract
The ability for changing lipophilic natural core model surface wettability and efficiency of static oil washing in East District 7(1)Xinjiang oilfield of four kinds of surfactant solution,Karamay petroleum sulfonate (KPS),sulfobetaine (BS),fatty amine polyoxyethylene ether (FAPE)and dodecyldimethylbenzylammonium chloride (1227 )were examined. Binary compound systems were composed separately using KPS,BS and FAPE with polyacrylamide (KYPAM-2 ). Then,interfacial tension against crude oil using solution of KPS/KYPAM- 2 ,BS/KYPAM - 2 and FAPE/KYPAM - 2 binary compound systems and 1227 solution was measured,and adhesion work needs to overcome for stripping the oil droplets from the rock surface by the binary compound system was calculated. Finally,oil displacement efficiency was studied using the above -mentioned binary compound systems and 1227 solution. The results showed that all of four kinds of surfactant solution can make the rock surface wettability reverse from oil-wetting to neutral wetting or aqueous wetting;where,the adhesion work of BS solution is 0.018 J;efficiency of static oil washing using BS is 85.7% and EOR magnitude after water flooding of BS/KYPAM -2 achieves 12.7%,which is the best among the four kinds of surfactant.关键词
