摘要：NOVELTY - An oil displacement system contains lipopeptide biological surfactant (6-120 mg/L), heavy alkylbenzene sulfonate (0.01-0.30 w/v%) and base (0.5-5 w/v%). USE - Oil displacement system for use in development of oil field (claimed). ADVANTAGE - The system includes lipopeptide biological surfactant which reduces usage of base and heavy alkylbenzene sulfonate, synchronously strengthens the interface activity of the system and increases the activity range of the system; and can be easily controlled and used.
