| 摘 要： | 为了使油田用助剂的乳化力的评定与实际工作环境更为吻合，实验改进了原有的国家标准，采用光度法进行了实验研究。确立了分析方法的最佳波长为230 nm附近，标准曲线绘制时的油含量选在300 mg/L以下时线性关系良好，乳化剂的用量在0.05%（质量分数）以上时具有较好的乳化现象，便于操作。给出了操作步骤和溶液配制规程，验证了该方法的误差、重现性和实用性，表明该法可以有效地评定油田用表面活性剂的乳化力。

| Abstract: | In order to determine the emulsifying ability of an emulsifier used in oil field more consistently with the actual working environment,this experiment result can improve the current national standards.For spectrophotometry method,the best wavelength is 230nm.The oil content for the standard curves should be controlled less than 300mg/L.The dosage of emulsifier should be more than 0.05%.The operation procedure of determination process and the solution preparation method were setup.The error,reproducibility and practicality of the method were verified.The results indicate that the method is an effective for evaluating the emulsifying ability of surfactants used in oil field. |
