摘要
利用有限元理论，着重分析了水平井实际钻进中的钻柱大变形非线性及钻柱与井壁的接触非线性问题，并独立导出了一套非线性有限元钻柱力学模式，在此基础上编制了一套非线性力学计算程序软件，并在海洋石油南海西部石油公司一个钻井平台进行了５口水平井钻井的实际验证，获得了一些带启迪性的结论。
By the method of finite element theory this paper emphasis its analysis on the nonlinear feature of great deformation of drilling rod and contact between drilling rod and well deck. A dynamic model of nonlinear finite element was established and programized for computer by the practice in 5wells some conclusion with inspiration was obtained
