摘要
通过对套管水压渗漏原因分析,指出为了达到合适的J值而使用过扭矩拧紧,使螺纹发生挤溃塑性变形是影响水压密封性的直接原因,从而找出了J值超差的影响因素,提出了解决方法,并列出了实际使用的效果。
Through the cause analysis of casing leak during hydro-test,the article points out that the cause is plastic deform on thread,and thread deform was caused by over tight on torque in order to meet the J value,also finds the elements affecting on tolerance of J value,raises the resolved method,and states the application result.
