摘　　要：考虑钻柱沿井深和井眼圆周方向的随机接触碰撞，建立起整体钻柱瞬态动力学分析模型，运用Ｎｅｗｍａｒｋ法求解钻柱动力平衡方程．通过理论分析计算结果与室内模拟实验实测结果的对比分析，进行了理论模型、分析方法与室内实验的互相验证．Considering the random contact and impact between drillstring and borehole wall in arbitrary depth and direction, a dynamic model of whole drillstring is established, and Newmark method is adopted to solve the dynamic equilibrium equation. By comparing the calculating results with the measured results of indoor simulating test, the theoretical model, analysis method and the indoor test are verified against each other, so a theoretical basis and verifying method is provided for further indoor test.
