聚氧乙烯醚类表面活性剂具有较好的耐温性和抗盐性，且驱油效果好，在三次采油中发挥着越来越重要的作用。介绍了近五年来国内外驱油用聚氧乙烯醚表面活性剂（非离子型和阴-非离子型）的研究进展，概述了聚氧乙烯醚表面活性剂与聚合物、碱或其他表面活性剂复配形成的驱油剂的性能和驱油效果，针对目前聚氧乙烯 醚表面活性剂在三次采油中存在的问题提出了建议。参37

Polyoxyethylene ether surfactant exhibited good temperature resistant，salt tolerant as well as oil displacement effect， which played an important role in tertiary oil recovery. The research progresses of polyoxyethylene ether surfactant for oil displacement，including nonionic surfactant and anionic-nonionic surfactant，in the last five years were reviewed. The performance and oil displacement efficiency of the mixture of polyoxyethylene ether surfactant，polymer and alkali，or other surfactants were summarized. The research suggestions were proposed for the problems existed in polyoxyethylene ether surfactant used in tertiary oil recovery.
