摘要
由于大位移井水平段长,井斜角较大造成岩屑携带困难,影响到钻井及完井作业的正常进行,甚至造成卡钻、填井、侧钻、整井报废等事故,造成重大经济损失。因此,及时有效地进行井眼清洁,清除岩屑是亟待研究解决的问题。本文针对上述问题,设计了大位移井井眼清洁工具,该工具具有三组特殊流型结构设计的扶正器,可起到降低岩屑床形成的几率,破坏已有岩屑床,清洗井眼,修整井壁的作用,进而提高井身质量及机械钻速,降低钻井风险,提高整体效益,并且现场应用效果明显。
Due to long horizontal section,big angle of inclination,it is difficult to remove cuttings that influence drilling and well completion,even lead to sticking、plug-back、side tracking、abandoned well.for this reason,hole cleaning and removing cuttings are first questions.Aiming at these difficulties,this article describes that hole cleaning tools with stabilizer of three special flow structures are researched to reduce formation rate of cuttings bed,destroy cuttings bed,clean hole,repair hole wall,thus further improve wellbore quality and drilling rate,reduce drilling risk,enhance profits,and applied successfully on the plot.
