摘要:
为了解决薄壁管材特殊螺纹接头在油田频繁出现高压泄漏的问题,采用有限元和实物试验相结合的方式,研究分析了薄壁管材特殊螺纹接头台肩厚度、螺纹过盈量和密封面结构等关键参数对接头密封性能的影响。结果表明,增大台肩厚度、降低螺纹过盈、设计锥/锥密封结构可大幅提高接头密封接触压力积分值,能够较好解决薄壁特殊螺纹油套管密封性能不足而导致的高压泄漏问题。根据该思路设计出常用规格的薄壁特殊螺纹套管,经实物试验验证,薄壁套管接头抗粘扣性能优异,密封性能达到了100%等管体,能够有效解决薄壁特殊螺纹接头上扣不稳定及高压漏失问题。
Abstract:
In order to solve the of high pressure leakage of the special threaded joints for thin-walled pipes applied in oil fields,adopting a combination of finite element analysis and full-scale test to analyse the influence of key parameters such as shoulder thickness, thread interferenceand sealing surface structure on the sealing performance of special threaded joints in thin-walled pipes.The results show that by increasing shoulder thickness, reducing thread interference and designing cone/cone sealing structure, the integral value of contact pressure of joint seal can be greatly improved, and the problem of high pressure leakage caused by insufficient sealing performance of thin-walled special thread oil casing can be better solved. According to this idea, two kinds of thin-walled special thread casing with common specifications are designed. The full-scale test proves that the two kinds of thin-walled special thread joints have excellent anti-sticking properties, and the sealing performance reaches 100% equal pipe body, which can effectively solve the problems of unstable screw-on and high pressure leakage of thin-walled special thread joints.
