理想等螺距管螺纹接头在轴向拉力作用下,扣牙力分布呈抛物线状,制约了管螺纹接头的承载能力。采用适当的变螺距工艺可使扣牙力分布得以改善,从而提高套管柱承载能力。本文用解析法求出了变螺距管螺纹接头扣牙力分布曲线,探讨了变距方式、变距量和变距点等问题。

The mechanism of jump out of threaded casing connection is researched by using a finite element analysis program (ADINA). Displacement constraint functions are applied to describe the magnitude of overlapping and contact condition. Probing contact condition and elasto plastic equilibrium iterations are adopted in studying the mechanical property of threaded casing connection in screw on and jump out respectively.
