摘　　要：机械式自动垂钻工具具有耐温性高、成本低、适用范围广等优点,是一种适用于深井和超深井控制井斜、提高垂直精度的重要技术手段。但由于其纠斜、防斜是靠重力及机械结构来实现的,在粘滑振动的工况下工作精度会受到巨大的影响。因此,本文从粘滑振动的产生机理出发,总结出其具体影响因素,并对现有国内外抑制粘滑振动的手段进行对比分析,寻求适用于机械式自动垂直钻具的可行粘滑振动抑制方法,为工具防斜纠斜能力的进一步提升提供可靠的技术保障。Mechanical automatic vertical drilling tools provide the advantages of high temperature resistance,low cost,wide application range,etc.;however,since the deviation correction and deviation prevention are realized by the gravitational and mechanical structure,the working accuracy under the condition of stick-slip vibration is greatly affected.This paper,with introduction to the stick-slip vibration mechanism,summarizes its concrete influence factors,and compares the existing methods to limit stick-slip vibration at home and abroad to explore suitable stick-slip vibration suppression methods for the mechanical automatic vertical drilling tools so as to provide reliable technical support for improvement of deviation prevention and correction capability.
