    • The present invention relates compositions and methods for enhanced oil recovery. The method is directed to employing a water-soluble fThe present invention relates compositions and methods for enhanced oil recovery (EOR). The method is directed to employing a water-soluble functional polymeric surfactant (FPS), with a medium IFT value, preferably ranged from about 0.1 to about15 dyne/cm between water phase containing polymeric surfactant and hydrocarbon phase, for recovery of hydrocarbons from subterranean formations. The FPS solution demonstrates a strong interaction with oil and the great potential to increase both volumetric sweep efficiency and microscopic displacement efficiency in EOR.
    • 本发明涉及用于强化油采收的组合物和方法。 该方法涉及使用水溶性油。本发明涉及用于提高油采收率(EOR)的组合物和方法。 该方法涉及使用水溶性官能聚合物表面活性剂(FPS),其具有介于中等IFT值,优选介于约0.1至约15达因/厘米之间的含有聚合物表面活性剂和烃相的水相,用于从地下地层采收烃 。 FPS解决方案表现出与石油的强烈相互作用,以及提高EOR体积扫描效率和微观驱油效率的巨大潜力。
