摘　　要：吉林油田经多年注水开发 ,地下流体流动性强 ,注入压力不断增加 ,导致调整井固井质量较差 ,为此 ,在大量试验的基础上 ,研究出防窜能力强的 NCD- 复合型调整井水泥浆外加剂 ,具有体积微膨、终凝时间短、早强、流动性好等优点 ,在 2 3口井的应用结果表明 ,固井合格率为 10 0 % ,固井优质率为 91.3%。Water injection development for many years causes the bad cementing qualities of the adjustment wells in Jilin oilfield. Therefore, based on a lots of tests, the NCD II complex additives are developed, which have many advantages, such as good anti channeling property, good conductivity, and so on. Field applications in 23 wells show that the qualification rate of cementing is 100% and the high quality rate is 91.3%.
