| 摘 要： | 通过对塔里木油田250.83 mm套管使用情况调研,发现目前使用的250.83 mm套管采用API 244.48 mm偏梯形螺纹接头,其连接强度远低于管体。设计了与250.83 mm套管管体匹配的250.83 mm非API规格偏梯形螺纹套管接头。通过力学计算和有限元分析,证实250.83 mm管体配250.83 mm非API规格偏梯形螺纹接头套管比现有250.83 mm管体配API 244.48 mm标准偏梯形螺纹接头的套管连接强度大幅度提高。通过对API标准套管接头连接强度公式进行分析,得出了既可满足API套管连接强度计算,又可满足非API标准套管接头连接强度计算的公式。 |

| Abstract: | An investigation on 250.83 mm casing used in Tarim oil field is given,and it was found that the tension strength of 250.83 mm casing with API 244.48 mm buttress thread connection was far less than that of its pipe body.The new 250.83 mm buttress thread connection was designed for 250.83 mm casing.It is proved that the tension strength of 250.83 mm casing with 250.83 mm buttress thread connection was far more than that of 250.83 mm casing with API 244.48 mm buttress thread connection per carrying out calcula... |
