钻杆拉力 meaning in Chinese

drill pipe tension

In consider drilling rod state , hole state , creep into course influence foundation of parameter synthetically , the drilling rod model under acting on the pulling force and torsion together carries on the theory to calculate , receive drilling rod pulling force and torsion differential equation group , in order to benefit drilling rod strength further to analyse
在综合考虑钻杆状况、钻孔状况、钻进过程参数的影响基础上，对拉力和扭矩共同作用下的钻杆模型进行理论计算，得到钻杆拉力一扭矩微分方程组，以利于钻杆受力的进一步分析。
