双作用钻具减振器由于其独特的结构而具有减缓或消除钻具纵向振动和扭转振动的双重功能。本文阐述了这种减振器的工作原理、二况受力分析及主要结构设计依据,可为使用这种减振器的钻井工程技术人员提供技术参考。
Due to its unique structure, dual-action drill shock absorber has the dual function of slowing down or eliminating longitudinal vibration and torsional vibration of drilling tools. This paper describes the working principle of the shock absorber, the second case of stress analysis and design of the main structure based on the shock absorber for the use of drilling engineers and technicians to provide technical reference.
