摘　　要：聚合物驱提高采收率技术为大庆油田稳产或增产提供了有效途径，并且已取得了显著成效。然而聚表剂（聚丙烯酰胺改性,表面活性基团连接到大分子链上，分为Ⅰ、Ⅱ、Ⅲ型）驱油技术在油田应用尚未成熟，Modified evaluation procedures were established for demulsifiers evaluationon polysurfactant flooding produced fluid.An effective demulsifier was developed forthe produced fluid by S1 polysurfatant flooding field trial.The newly developed demulsifier was evaluated on the produced fluid of a central producer at various stages of the S1 polysurfactant flood project.The test results demonstrate the applicability of the newly developed demulsifier on the produced fluid at various stages of polysurfactant flooding.
