It is shown that the contact interaction enables bottom drillstring to whirl backward, and then an alternate bending stress with higher frequency is produced. So the drillstring fatigue failure could be accelerated. At the same time, a quite strong wallop force of high frequency is produced on the contacting point, and the contacting zone is next to the screw coupling of drill collars. It will easily result in the failure of screw couplings. The research results provide theoretical basis for the prevention of drillstring failure.
研究表明,下部钻柱与井壁的碰摩作用使下部钻柱反向涡动,产生高频的交变弯曲应力,会加速下部钻柱疲劳破坏;下部钻柱与井壁接触点处存在较大的高频冲击力,并且接触区域靠近钻铤螺纹联结处,更容易诱发螺纹联结处失效,该研究成果可为预防钻柱失效提供理论依据。

Bolt with full screw threads and equal strength is a new type of bolt.
全螺纹等强度锚杆是一种新型锚杆,其最主要优点是杆体不需二次加工紧固螺纹,不仅简化了生产工艺,还实现了杆体全长等强,克服了常规锚杆受拉时产生应力集中区而使杆体强度降低的缺点,另外,较大的螺距可使锚杆安装速度提高。

2 The provisions of valve flap stent thrust nut in space; 4.3 will bring more than ejector stem components, and into the valve flap bracket, now can adjust screw ring on the injector; adjustment ring discharge pipe may be twisted too high in case of this case, when the valve assembly after the valve flap in contact with its seat before the valve flap seat will have an additional load on the adjustment ring edge, in order to avoid this from happening, should enable the adjustment ring hole just below the injector thread, through which holes should not be able to see thread.
4.2 规定阀瓣支架与止推螺母中的间隙; 4.3 将喷射器提起超过阀杆组件,并放到阀瓣支架上,现在可以把调节环拧在喷射器上;调节环可能在排放管上拧得太高,如遇此情况,当阀门组装后,在阀瓣与其座相接触前,阀瓣座将加载荷于调节环的边上,为了避免此情况的发生,应使调节环上的孔正好低于喷射器的螺纹,通过这些孔应不能看到螺纹。
