| 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。

| Abstract: | 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. |

| Keywords: | vertical drilling mechanical vertical drilling tool correction stick-slip vibration suppression method |
