合成了强阴离子交换及硅胶基质ODS键合高效液相色谱(HPLC)柱填料。针对胜利油田复合(碱+表面活性剂+聚合物)驱油工程实施的需要，建立了适合于注采液中表面活性剂PS的HPLC分析方法。该方法对PS标准样品的最小检出限为0．4 mg/L，线性范围为50 mg/L～1*!000 mg/L，回收率为95．7%～99．8%。实践证明，该方法的建立为油田的复合驱油配方设计、注入方案调整、产品质量监控及驱油机理研究等提供了有力的技术支持。
Ion exchanger and ODS bonded silica gel for HPLC packing were prepared． An HPLC method for the analysis of surfactant PS concentration in injected-produced liquor has been established to meet the need of ASP flooding developed in Gudao West Block of Shengli Oilfield, with a minimum detectable limit of 0．4 mg/L, a linear range of 50 mg/L-1*!000 mg/L and recoveries of 95．7%-99．8%． This method has provided great technical support in a variety of fields to the design of the prescription for ASP flooding, the regulation of injection measurement, the quality control of products and the study on the mechanism of oil flooding etc．
