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。
KW-1 high-temperature oil displacement aid is a film extender. The main mechanism of its role peel role, demulsification effect, change the role of phase permeability and expand the role of volume and spread. Through static test evaluation, high temperature and high pressure injection capability evaluation and high temperature and high pressure dynamic flooding efficiency evaluation of indoor evaluation studies and field application studies, KW-1 high temperature oil displacement agent is an ideal heavy oil thermal recovery additive. And summed up the application of KW-1 (well selection) conditions and application considerations.
