在分析水平井管柱空间受力平衡的基础上， 考虑了管柱刚度附加的接触力与曲率半径的三次方成反比以及管柱末端效应对轴向力和法向力的影响， 采用迭代计算方法， 建立了水平井管柱空间受力的三维求解模型。利用这种模型， 对现场一水平井的管柱受力特性进行了计算， 结果表明， 迭代计算方法可以简化空间问题， 便于计算机处理数据， 比平面分析方法更为有效， 为合理选用水平井管柱提供了依据。
Based on the analysis of the force balance of the horizontal well string, the effect of the additional contact force of the column stiffness on the cube of the radius of curvature and the effect of the end effect of the column on the axial force and the normal force are considered. The iterative calculation Method, a three-dimensional solution model of the horizontal force of the horizontal well string is established. The model was used to calculate the force characteristics of a horizontal well in the field. The results show that the iterative method can simplify the space problem, make it easier for the computer to process the data and is more effective than the plane analysis method. Column provides the basis.
