| 摘 要： | Using premium casing connections instead of API ones is one of the most effective technique to prevent casing failure. The factors contribute to the strength of premium casing connections are studied with FEA and full-scale test. The criterions are presented that ensure the connection's strength higher than the pipe. At the same time, the method is given to decrease the peak stress of the connection so as to improve its anticorruption property. At last, full-scale tests are done to test the strength of the connections designed with the method described, the results show that the connection's strength is higher than the pipe. This indicated that the method described is effective in designing premium casing connection.
