摘　　要：本文对碱法造纸黑液胶凝反应原理和凝胶的综合性能作了研究，并介绍了在新疆克拉玛依油田九１－３区１０口注蒸汽井进行蒸汽驱调剖现场试验的情况。试验结果表明：调剖剂配制液粘度低，易泵入，成胶时间可控制在８－４８ｈ，凝胶堵塞强度较高，成功率１００％，有效期平均在７个月以上，增油减水效果明显，投入产出比高达１∶７，具有良好的经济效益。The gellihng reaction of alkaline black liquor,phenol,aldehyde and crosslinking agent and the properties of the gel formed are investigated in this paper. The gelation time varies in the range 8-48 hrs at temperatures 150-300℃. The steam-plugging efficiency determined in quartz sand pack tests with this profile modificator at 200℃ is of>94 %. Field tests in 10 steam injecting wells in area IX-1-3 of Karamay Oil Fields are all successful and of 52 producing wells oil output raise is observed in 20 wells.
