【摘要】 在分析抽油杆柱载荷的基础上，从定向井抽油杆柱通常装有多个导向扶正器的特点出发，应用纵横弯曲连续梁理论给出求解带扶正器的抽油杆柱任意截面处轴力、弯矩和挠度的计算公式。进而以ＡＰＩ推荐的强度设计准则作为设计依据，提出了有利于直井的定向井抽油杆柱组合设计程序，并给出了计算程序框图。最后以某油田某井作实例，给出了计算参数和设计结果。更多还原

【Abstract】 On the basis of an analysis of the load on the sucker rod string with many guiding stabilizers, and by the crossbar bending continuous beam theory, the authors work out the equations for calculating the axial force, bending moment and deflection on any arbitrary crosssection of the rod string. And according to the strength design criteria recommended by API, the authors present the computer program and program chart for the design and calculation of the rod string for directional holes, and give an example.更多还原
