摘要:
分析了API套管螺纹接头的泄漏机理以及特殊螺纹接头的密封机理,在API套管螺纹接头的结构基础上进行了一定改进,提出了一种新型的双台肩、三锥度套管特殊螺纹接头的密封结构形式,并利用ANSYS软件对设计的密封结构在上扣和拉伸两种工况下进行了分析研究,得出了不同工况下螺纹接头各扣牙的受力曲线。分析结果表明,该特殊螺纹接头结构合理,各扣牙受力分布较为均匀,可延长套管接头的使用寿命。

Abstract:
In this article, it analyzed leakage mechanism of API casing thread joint and sealing mechanism of premium thread joint, and put forward a new kind of sealing structure for casing premium thread joint with double shoulder and three taper, which was improved based on API casing thread joint. Using ANSYS to study the designed sealing structure on two condition of screwing on and stretching, a stress curve of joint buckling thread was obtained under different conditions. The analysis results demonstrated that this kind of premium thread joint is with reasonable structure, the distribution of buckling thread stress is uniform, which can prolong the application life of casing joint.
Key words: thread connection; leakage mechanism; sealing mechanism; force analysis
