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 anti-skew and skew mechanism of flexible anti-skew and skew-inclined drill assembly is introduced. Its mechanical model is given and analyzed. The technical measures for anti-skew and skew drilling are put forward. The application of Borgon wells shows that the combination of drilling tools can effectively control the increase of the inclination of the well and has the function of lowering the slope and increasing the rate of the ROP, and provides the rapid anti-inclined and inclined drilling for the inclined zone with large dip angle A new type of drill assembly.
