摘要: 在超短半径水平井侧钻技术中，柔性钻杆与导向筛管、钻头与岩石之间频繁地摩擦碰撞，可能导致柔性钻具因发生耦合振动而失效破坏，直接影响钻井安全和钻井效率.选取造斜段铰接式柔性钻具为研究对象，考虑柔性钻杆与导向筛管之间的接触非线性以及井底岩石对钻头的作用力影响，建立了造斜段铰接式柔性钻具耦合振动力学及有限元模型.通过对铰接式柔性钻具进行耦合振动动力响应分析，得到铰接式柔性钻具各方向的变形图以及不同位置柔性钻杆的横纵扭振动加速度响应曲线，然后讨论了钻压、转速对铰接式柔性钻具耦合振动特性的影响.结果表明：越靠近钻头处，柔性钻杆横向振动越剧烈，而扭转振动随井深呈周期性递减；钻压越大，柔性钻杆横向和扭转振动越大；转速越大，柔性钻杆横向振动越小，而纵向振动和扭转振动的变化受转速影响较小.Abstract: The frequent frictional collision between flexible drilling pipe and guide screen as well as drill bit and rock may lead to the failure of flexible drill pipe due to coupling vibration in the side-drilling technology of ultra-short radius horizontal wells, which directly affects drilling safety and efficiency. The coupling vibration mechanics and the finite element model for the articulated flexible drilling tool in the inclined section were established with the contact nonlinearity between flexible drilling pipe and guiding screen and effects of rock force on drill bit. The deformation diagrams of the articulated flexible drilling tool and the acceleration curves of the transverse, longitudinal and torsional vibrations of the flexible drilling tool in different positions, were obtained by analyses of the coupling vibration dynamic responses of the articulated flexible drilling tool. And the effects of bit weights and rotational speeds on the coupled vibration characteristics of articulated flexible drilling tools were discussed. The results show that, the lateral vibration of the flexible drill pipe becomes more severe as the drill is closer to the bit, while the torsional vibration decreases periodically with the well depth. The larger the bit weight is, the bigger the lateral and torsional vibrations of the flexible drilling pipe will be; the larger the rotational speed is, the smaller the lateral vibration of the flexible drilling pipe will be; the longitudinal and torsional vibrations is less affected by the rotational speed.
