摘　　要：ＫＷ－１高温驱油助剂是一种薄膜扩展剂。其主要作用机理有剥离作用、破乳作用、改变相渗透率作用和扩大波及体积作用。通过静态试验评价，高温、高压注入能力评价及高温高压动态驱油效率评价等室内评价研究和现场应用研究，证明ＫＷ－１高温驱油助剂是比较理想的稠油热采添加剂。并总结出ＫＷ－１的应用（选井）条件和应用注意事项。W-1 high temperature oil displacement assistant is a kind of thin film spreading agent,its function mechanisms mainly include peeling,demulsification,improving phase permeabili-ty,and increasing sweep volume.KW-1 high temperature oil displacement assistant is provedto be a kind of ideal additive for thermal oil recovery through laboratory evaluation,based onthe static experimental evaluation,injectivity evaluation and dynamic oil displacement effi-ciency evaluation under high temperature and high pressure,and studies of field application.The conditions and considerations for the application of KW-1 have been summarized.
