Sodium dodecyl benzene sulfonate(SDBS) and compound systems which included SDBS and two kind of inorganic alkali(NaOH, Na2CO3), SDBS and two kind of organic alkali(triethylamine and monoethanolamine) were used to prepare emulsion with crude oil. Syneresis rate is used as the main index to analyze the stability of emulsion. The optimum concentrations are obtained for SDBS and alkali, they can produce significant synergistic effect and get stable emulsion with low syneresis rate(less than 15%) in this condition. The micro-morphology analysis method is used to compare and analyze emulsion that prepared by different kinds of SDBS-alkali compound system with the same concentrations. The amount of emulsified oil droplets is larger; the particle size is smaller and coalescence is not easy to happen when alkali exists. Compared with SDBS-inorganic alkali compound system, the emulsified effect of SDBS-organic alkali compound system is better.
