摘　　要：为了减少因钻柱在钻进过程中产生的复杂振动造成的损失,在原有减振器的基础上设计了一种新型减振器。首先对钻柱的振动特性及其横向振动进行了研究;其次基于钻柱横向振动研究,设计出随钻测井仪减振器机械结构并阐明其工作原理;最后对减振器的性能进行了仿真验证。The drill string will produce complex vibration in the process of drilling,which will affect the performance of logging tool while drilling,and even lead to the damage of the tool,resulting in downhole accidents.In order to achieve good damping effect,it is necessary to optimize the design based on the original shock absorber.Firstly,the vibration characteristics of the drill string are studied,and the lateral vibration is designed.Secondly,the mechanical structure and working principle of the vibration damper of LWD are designed based on the research of the lateral vibration of the drill string.Finally,the performance parameters of the vibration damper are verified.
