摘要
该文介绍了克拉玛依油田二中区ＡＳＰ驱中石油磺酸盐在油水两相中的分配系数研究成果。考察了盐浓度、碱浓度和磺酸盐浓度对分配系数的影响，结合二中区ＡＳＰ驱，给出了ＡＳＰ配方中磺酸盐在油水比（体积）为１∶１时的分配系数。文中还介绍了用多维液相色谱法分析原油中的石油磺酸盐。该项研究为其它相关研究提供了重要依据。
This paper presents the research on partition coefficient of petroleum sulfonate in oil and water phases of ASP flooding in block II of Karamay oil field. The influences of salt, alkali and sulfonate on partition coefficient were studied. Based on the ASP flooding in block II of Karamay oil field, the partition coefficient of sulfonate in ASP flooding when the water oil ratio equals 1∶1 is given. This paper also discusses the method of determining petroleum sulphonate in crude oil by multi dimensional liquid chromatography. This study provides important basis for related researches and is of certain guiding significance to field test.
