| 摘 要： | 采用有限元法开展气体钻井全井段钻柱的非线性动力学运动过程模拟研究。建立了某井全井段塔式钻具的三维模型和钻头与岩石以及钻柱与井筒之间的接触关系,分析了钻柱在动态钻进过程中的力学参数,得出气体钻井全井段钻柱的运动规律以及对钻柱寿命的影响。对气体钻井中钻柱力学、井斜控制等方面的深入研究具有指导意义。

| Abstract: | Simulation study on non-linear dynamical movement of entire drilling string in gas drilling is carried out to adopt finite element method(FEM).The 3D model of entire tapered drillstring and contact relation of bit-rock and drillstring-wellwall is established and the result of serial mechanic parameter is analyzed to get the rule of entire drillstring movement and the effect with fatigue life.The conclusion is useful to study drilling string mechanics and hole deviation in air drilling. |
