介绍了胜利油田河９０－平１井和盘４０－４１侧平１井两口短半径水平井钻井液体系选择及应用情况。分析了两口井钻井液技术要点，探讨了钻井液流变性能控制、泵排量选择、保护油层等方面问题。两口井钻井实践表明，正电胶及强抑制性聚合物钻井液体系及相应技术措施适合于该类型短半径水平井钻井施工。
This paper introduces the selection and application of drilling fluid system of two short radius horizontal wells in He 90-Ping 1 and He Ping 1 wells in Pan 40-41 of Shengli Oilfield. The technical points of drilling fluid in the two wells were analyzed. The problems of drilling fluid rheology control, pump displacement selection and reservoir protection were discussed. The drilling practice of the two wells shows that the system and the corresponding technical measures of the positive gel and the strong inhibition polymer drilling fluid are suitable for drilling of this type of short radius horizontal well.
