摘要
介绍了柔性防斜纠斜钻具组合的防斜纠斜机理，给出了其力学模型并进行了分析，提出了其防斜纠斜钻进技术措施。在勃参一井的应用表明，该钻具组合能有效地控制井斜的增加并具有降斜的作用且能提高机械钻速，为大倾角硬地层易斜区快速防斜纠斜钻进提供了一种新的钻具组合类型。
The mechanism and mechanics model of the flexible bottomhole assembly for devition preventing and hole straightening are disscussed and analysed,and the drilling techniques for deviation preventing and hole straightening are put forwards.The application in Bocan 1 Well shows that the bottomhole assembly can effectively control well deviation and increase the drilling rate,a new type bottom hole assembly is provided to drilling in high angle deviated and hard formation.
