摘　　要：分析碱液的种类和质量分数、油酸的质量分数、矿化度,以及聚合物对碱水煤油乳化效果的影响,得出在45℃条件下,碱水煤油乳化的最佳条件为油酸在油相中的质量分数为4.0%,Na2CO3在污水中的质量分数为0.4%;此时平均粒径为2.514μm,矿化度对乳化效果影响不大,聚合物的加入反而增大了乳化体系碱的质量分数.We discussed the factors that influenced emulsification systems formed by alkali and kerosene,these factors mainly included the category of alkali,the concentration of oleic acid and alkali,and the salinity of water phase and HPAM.The best condition of emulsification at 45 ℃ was that the concentration of oleic acid is 4.0%,the concentration of sodium carbonate was 0.4%,the average diameter of particle was 2.514,the effect of salinity on emulsification was not apparent,and the concentration of alkali could be increased when polymer was added.
