摘　　要：本文提出了准确测定表面活性剂驱油试验产出液中表面活性剂与原油含量的简便方法,即在产出液中加入适量异丙醇使三相体系变成界面清晰的两相体系,然后分别测定二者含量。驱油试验的实测结果表明该方法是准确和适用的。When a certaiu amount of isopropyl alcohol is added into produced liquids in the surfac- tant and micelle/polymer flooding tests,the microemulsion forming oil/mineralized water (or with polymer)/surfactant systems can readily be transformed into two-phase(oil/wa- ter)systems with a distinct phase interface and volumometric determination of the oil and two-phase titration of the anionic surfactant in these systems may be performed quickly and accurately.The measuring results for a lot of such systems show that the suggested proce- dure is accurate and applicable.
