SDBS与APG1214复配对稠油协同增效的影响
Synergistic Effect of SDBS and APG1214 on Heavy Oil
摘要
Abstract
Using the synergistic effect of surfactant mixture to reduce oil-water interfacial tension and crude oil viscosity is an important method to improve oil recovery in recent years.The content of each component of crude oil produced from each oil field is different,so it is necessary to screen the suitable surfactant according to the component content.In this paper,the interfacial tension and emulsifying properties of sodium dodecyl benzene sulfonate(SDBS)and lauryl glucoside(APG1214)in Liaohe crude oil were studied by rotating drop interfacial tensiometer and bottle test method.The interfacial tension was studied by changing different compounding ratios,salinity and pH value,and the viscosity of the emulsion was measured by viscometer.The results show that the interfacial tension between oil and water can be reduced and the stable heavy oil emulsion can be formed by adding proper amount of inorganic salt in combination of surfactant.关键词
