| 摘 要： | 在定向钻穿越铺管的过程中,管道在孔内的受力情况非常复杂,但是回拖力计算又是机具选择的重要参考依据,所以管道受力分析及回拖力计算就显得非常重要。通过分析管道在弯曲段和稳定段的受力情况,分别建立管道弯曲段和稳定段的受力模型,最终总结出计算管道回拖力的方法。经实例计算检验,这种计算方法更加接近实际。

| Abstract: | The stress state of in-hole pipe is very complicated in pipe-laying in directional drilling,and pull-back force is the main clue when choosing the drilling rig.Therefore,stress state analysis and calculation of pull-back force play significant role in directional crossing pipe-laying.By analyzing stress state of pipe in both flexure and steady division,the force model is established.And eventually,the actual case verified that this calculation method was more actual and more accurate. |
