离子液体具有毒性低、无腐蚀性、在水和有机液体中的溶解度高、耐恶劣环境等特点，被广泛应用于石油工业的各个领域，但作为油田驱油化学剂使用则相对较少。通过梳理离子液体的驱油机理、技术优势与局限性，介绍了离子液体作为表面活性剂驱油的影响因素、优缺点以及与各驱油剂的协同应用，指出了离子液体表面活性剂的发展方向以及今后研究过程中亟需解决的问题。参48

Ionic liquid has the characteristics of low toxicity，no-corrosion，high solubility in water and organic liquid，and resistance to harsh environment. It is widely used in various fields of petroleum industry，but it is relatively less used as flooding chemical agent. This paper introduced the influencing factors，advantages and disadvantages of ionic liquid as surfactant in flooding，as well as its synergistic application with various oil displacement agents，and pointed out the development direction of ionic liquid surfactant and the problems to be solved in the future research process.
