油田用非离子型及阴-非离子型表面活性剂的应用进展

Application Progress of Nonionic and Anionic-Nonionic Surfactants Used in Oil Field

简述了国内外油田用非离子、阴-非离子表面活性剂的研究现状,介绍了非离子、阴-非离子表面活性剂在油田中应用进展,并探讨了两种表面活性剂与其它类型表面活性剂复配的应用前景。

Nonionic and anionic-nonionic surfactants possess the potential to be used in oil field because of their unique properties.In this paper,the domestic latest research progresses and the application feasibility of nonionic and anionic-nonionic surfactants were briefed;meanwhile,the research status of oil-displacing nonionic and anionic-nonionic surfactants was introduced.Finally,the prospect of application of the combination surfactants with the two types was also briefly mentioned.
