摘　　要：为了减小钻井过程中因轴向振动造成的钻柱和钻头破坏,文章研制了一种可伸缩式隔振器。该工具使用时安装在钻柱中和点以上,通过自身的轴向伸缩机构将上部钻柱和下部钻头产生的轴向振动隔断吸收,避免共振问题,减小底部轴向振动对上部钻柱和顶驱的破坏,同时增加了整体钻柱柔性,改善了钻头受力情况,有效减少钻头崩齿现象。在实际使用中,可伸缩式隔振器的最优安装位置可根据钻柱中和点及轴向振动最大处计算结果来综合决定。现场应用表明,可伸缩式隔振器对顶驱能起到很好的隔振保护作用,振动声幅降低了87%,同时出井钻头新度95%以上,减少了钻头钻遇砾石层的崩齿破坏。可伸缩式隔振器可作为钻井一开的标配工具,降低一开钻井过程中的振动危害,保护顶驱,减少钻井安全事故。In order to reduce the damage to the drill string and bit caused by longitudinal vibration during drilling,a retractable vibration isolator is developed.The tool is installed above the neutral point of the drill string,which can isolate and absorb the axial vibration generated by the upper drill string and lower bit through its own axial expansion mechanism to avoid resonance problems and reduce the damage to the upper drill string and top drive drilling system,and increase the flexibility of the drill string to improve force on bit and prevent the bit from chipped cutter.In practice,the optimal installation position of the tool is determined based on the calculation results at the neutralization point of the drilling column and the maximum axial vibration.The field application showed that the vibration isolator has played a good role in vibration isolation and protection of the top drive drilling system,and the vibration amplitude has been reduced by 87%,while the newness of the drill bit is more than 95%,and the chipped cutter of the bit drilling in the gravel layer has been reduced.It is recommended that the vibration isolator should be used as a standard tool for first spud to protect the top drive drilling system and reduce the drilling safety accidents caused by axial vibration.
