摘　　要：介绍了调剖剂XJF的配方,讨论了影响调剖剂性能的配方因素(膨润土含量、HPAM溶液浓度、XJ用量及添加剂Fc的浓度),考察了封堵能力和应用范围,简介了在火烧山油田现场试验的结果。An injectivity-profile modificator for use in water-injecting wells, XJF, is prepared from a PHPAM polymer with DH 30%, MM 3-4×10~, a local bentonite, a gelling/promoting agent, XJ(a silicate compound),and an organic disperssant/stabilizer for bentonite mud, Fc. The basic formulation of the profile modificator and the effects of composition variables on its viscosity and gelling are presented. In laboratory core tests plugging rates higher than 99% are observed with XJF. The field tests in 4 wells in Huoshaoshan Oil Field, North Xinjiang, gave fairly good results.
