摘要
根据套管螺纹接头的结构和受载特点，在先期建立的套管接头螺纹旋合接触的有限元分析模型和分析程序的基础上，研究了因加工误差而造成套管接头内、外螺纹螺距不一致时对其载荷传递特性的影响；给出了在内、外螺纹具有不同的螺距配合时，载荷在套管接头各扣螺纹上的分布规律曲线，为设计时合理选择套管接头内、外螺纹的螺距公差提供了依据．
According to the structure and load characteristics of casing thread joints, analysis are made using the finite element mixed method and object oriented programming technique. The influence of pitch errors on loaded casing thread joints is studied. The load distributions on each casing thread are given for different pitch fitting of the internal and external threads. Selection of pitch tolerance of casing threads could thus be made for references in design.
