摘　　要：分析了大斜度定向井、水平井的特殊性及不利因素。通过室内模拟试验和现场实践,较好地解决了大斜度定向井和水平井泥浆的润滑防卡、井眼稳定、携岩洗井及防漏堵漏等关键技术问题。胜利油田应用SN—1水包油泥浆、SN—2正电胶泥浆,完成了不同类型的水平井30口,其中在稠油砾石油藏完成无技术套管长裸眼水平井15口,未发生粘附卡钻或其它泥浆事故。By analyzing 30 horizontal wells drilled in Shengli oilfield in recent years , drilling problems encountered and measures to deal with them are presented . SN - 1 oil in water mud and SN - 2 cationic gel mud were used in the drilling of these wells . Mud properties required in horizontal drilling for Shengli oil field are given .
