提高重烷基苯磺酸质量稳定性研究

摘要

Three tens of thousands of t/a sulfonate units are used to produce three surfactant surfactants,heavy alkyl benzene sulfonates.Heavy alkyl benzene sulfonate surfactant and polymer,alkali form a ternary complex flooding system,the third oil recovery in the oil effect is remarkable,based on the water flooding recovery of 18% on average.Practice has proved that oil displacement table agent products Daqing Oilfield 40 million t steady production of great significance.The key raw material for sulfonate production is heavy alkyl benzene sulfonic acid.Whether the quality of sulfonic acid is stable or not depends on whether sulfonate formula can be successfully formulated,produced and injected.%3万t/a磺酸盐装置生产采用表活剂-重烷基苯磺酸盐.重烷基苯磺酸盐表面活性剂与聚合物、碱形成三元复合驱油体系,在油田三次采油中效果显著,在水驱基础上平均提高采收率18%.实践证明,驱油用表活剂产品对大庆油田4000万t稳产有重大意义.磺酸盐生产的关键原料为重烷基苯磺酸.磺酸质量的稳定与否关系着磺酸盐配方是否能够成功调配、生产、注入.
