By analysing and calculating the variations in distribution of axis direction contact force and contact pressure on screw thread, the influence of errors of pitch and taper of casing screw threads to the properties of resisting pull and sealing liquid and gas are studied. Based on the result obtained through analysis, a reasonable tolerance distribution for pitch and taper is proposed.

最后，本文通过分析计算内外螺纹不同的螺距、锥度参数配合时，轴向载荷及接触压力在螺纹上分布的变化，研究了套管螺纹的螺距、锥度参数误差对套管螺纹接头的拉伸和密封性能的影响，并依据分析结果提出了二参数公差带的合理分布。
