Abstract: A new type of single component chemical displacing agent 108 twinned FPS was polymerized which grafts the specially designed and optionized functional groups on the polycrylamide hydrocarbon chain. Its emulsifying performance and viscosity aging stability were invertigated, and a laboratory physical simulation oil displacement experiment was perfrmed. The results indicat that the FPS is characterized by the strong saltresisting, antioxidating and antibiodegradation performances, being suitable to prepare with the oil field waste water. It also possesses the oil solubility, emulsifiability, and viscosity enhancement properties, has better oil displacement effect than common polymer and ASP system.
