| 摘 要： | 油套管接头在油气田工业中已得到广泛使用，其密封性能对油气井生产安全与环境将产生重要影响。以上扣拧紧时的螺纹接头为研究对象，在弹性范围内构建了锥螺纹接头端部密封面上挤压力的计算方法。利用粗糙密封表面微观接触分析方法，以某一具体的API圆螺纹接头为例数值模拟了拧紧力矩（圈数）、表面粗糙度和初始密封面间隙对端面密封性能的影响规律，获得了相应的变化曲线，并对这些曲线进行了分析。

| Abstract: | Tubing and casing connections are widely used in oil and natural gas industry.Their seal performance is very important for circumstance and production safety in oil and gas well.In this paper,the threaded connections in the tightening condition are taken as research objects and a calculation approach to the squeezing force on the shouldered seal face of a conical threaded connection is established in the elastic range.By the method of micro contact analysis on sealing rough surface,API round threaded casing connection is taken as the calculating sample,and the influences of tightening torque (tightening cycles),roughness and initial seal clearance on the seal performance of the shouldered face are numerically simulated.And the concrete variation curves are obtained and analyzed in detail. |
