文中分析了使用偏轴接头对钻具各部分受力情况的影响及导致钻具失效的原因。
This paper analyses the influence of excentric shaft connection on force case of drill tool, and discusses the causes of drill tool failure.
为了达到较好的防斜目的,必须增大钻进时钻头的转速,在高转速的作用下,偏轴接头加剧了钻具先期疲劳失效。
By the action of high roatry speed, excentric shaft connection intensifies the fatigue failure of drill tool.
该模型能够用于求解钻头处的侧向力和转角以及偏轴接头处的侧向力,以评价钻具组合的防斜(纠斜)能力和偏轴接头附近的偏磨程度。
The lateral force on offset-axes sub can be calculated and used to evaluate the eccentrically wearing degree near the offset-axes sub.
