| 摘 要： | 从钻井连续循环系统卡瓦的工作原理入手,分析了横向载荷与方瓦摩擦力的关系,揭示了卡在卡瓦中的钻杆的受力状态.将钻杆看作厚壁筒,采用弹性力学中的拉美公式求解钻杆内外受压的应力问题.钻杆外表面承受的摩擦力矩,看作圆筒扭转问题进行求解.考虑钻柱轴向拉力的影响,解决了钻井连续循环系统卡瓦极限卡紧力的计算难题,给出了卡瓦极限卡紧力的计算公式.以5吋和5.5吋钻杆作为算例,分析了钻井连续循环系统的使用范围,提出了钻井连续循环系统对钻杆钢级的要求.该方法可以用于指导钻井连续循环系统卡瓦的设计. |

| Abstract: | Based on the operational principle of the slip in continuous circulation drilling system,the relationship between lateral load and the friction of master-bushing with slip is analyzed,and the forced state of the drillng pipe in the slip is presented.Taking the drilling pipe as thick-wall cylinder,the stress of it is solved with the Lame equation.The friction torque acted on the outer surface of the drilling pipe is treated as torsion moment in the stress calculation.Under considering the axial tension of th... |
