定向井井眼轨迹的连续控制

WELL PATH CONTINUOUS CONTROLLING IN DIRECTIONAL WELL

    摘要
  • 摘要: 目前,大多数定向井采用常规的钻井工艺技术进行井眼轨迹的控制(即非连续控制),一口井要改变钻具结构多次,而每次改变钻具结构需起下钻方能实现。导向钻井系统可实现井眼轨迹的连续控制,靠一套多功能下部钻具组合一次下井,配合长寿命的优质钻头和随钻测斜仪导向,在井下长时间运转,不用起下钻就能准确、连续、迅速、经济地完成定向井多种井段的作业。该技术的推广应用,将会取得很大的经济效益。

     

    Abstract: Up to now, much directional well using conventional technology to control well path that requires often changing the BHA and cost drilling time. The steering drilling system can continuously control well path by using one set of navigational BHA (bottom hole assembly) with edvanced bit and MWD (Measurement while Drilling) to teduce tripping time to realize,accuracy,continousy and economical directional drilling work.
