摘要
本文以100m以内工程钻进的钻杆柱为研究对象,以TH50C-T钻机为实验平台,利用建模试验与CAE有限元仿真软件ANSYS进行分析。在考虑接头影响和钻头几何尺寸条件下对钻杆柱进行分析,得到的钻杆柱结构与钻压、扭矩、变形及各测点应力之间关系具有意义的认识,对钻杆认识的全面性提供有力的保障,为钻杆的优化设计提供重要的参考依据,对工程钻进具有一定的指导意义。
This paper is researching and analyzing drilling stem （〈100 meter） in engineering by modeling test on TH50C-T drilling machine and software ANNYN on FEM of CAE technology. Considering colmecting and drilling head, analyze the drilling stem. we get significant knowledge between the structure of drilling stem with the pressure of drilling, torque, strain, stress. It can improve our knowledge about drilling stem more completely and supply the important reference to optimize the drilling structure.
