The premium casing connection is composed of three parts: the main sealing structure, the reverse shoulder structure and the thread. The angle θ of the reverse shoulder has an important influence on the strength and sealing performance of the premium casing connection. Based on the idea of factor rotation method, the influence of parameter θ on the maximum contact pressure of the main sealing surface of the premium casing connection, the contact pressure of the shoulder surface and the internal stress of the connection is studied through finite element simulation experiments. The results show that the greater the angle of the reverse shoulder, the better the sealing performance of the connection, but the worse the anti-torsion ability of the connection.
