连续油管调研情况一、常用的连续油管性能参数连续油管 (Coiled Tubing，简称 CT)又称挠性油管、盘管或柔管。相对于用螺纹连接的常规油管而言，连续油管(CT)是卷绕在卷筒上拉直后直接下井的长油管。连续油管作业最初用于下入生产油管内完成特定的修井作业(如洗井、打捞等 )。到上世纪 90 年代，连续油管作业装置己被誉为“万能作业设备”，广泛应用于油气田修井、钻井、完井、测井等作业，在油气田勘探与开发中发挥越来越重要的作用。表 1 常用的连续油管性能参数外径mm 壁厚mm 内径mm 单位重量kg 最大载荷kN 屈服强度MPa 试验压力MPa 爆破极限MPa 25.4 1.702 22 1.024 58.9 48.6 60.8 25.4 1.905 21.59 1.103 65.8 54.8 68.5 25.4 2.21 20.99 1.262 76 64.1 80.1 25.4 2.413 20.57 1.366 82.5 70.2 87.8 25.4 2.591 20.22 1.455 87.4 74.9 93.6 25.4 2.769 19.86 1.543 93 80.3 100.3 31.75 1.905 27.94 1.400 83.5 43.8 54.8 31.75 2.21 27.33 1.609 96.6 51.2 64.1 31.75 2.413 26.92 1.744 105.2 56.2 70.2 31.75 2.591 26.57 1.860 111.6 59.9 74.9 31.75 2.769 26.21 1.976 118.9 64.2 80.3 31.75 3.175 25.4 2.241 133.2 72.8 91.1 31.75 3.404 24.94 2.377 143.2 79 98.8 31.75 3.962 23.83 2.738 162.7 91.4 107.3 38.1 2.413 33.27 2.212 128 46.8 58.5 38.1 2.591 32.92 2.265 135.8 49.9 62.4 38.1 2.769 3.55 2.409 144.8 53.5 66.9 38.1 3.175 31.75 2.732 162.7 61.2 76.5 38.1 3.404 31.29 2.909 175.2 65.8 82.3 38.1 3.962 30.18 3.341 199.8 76.1 95.2 44.45 2.769 38.92 2.842 170.8 45.9 57.3 44.45 3.175 38.1 3.259 192.1 52 65 44.45 3.404 37.64 3.442 207.1 56.4 70.6 44.45 3.962 36.53 3.959 236.5 65.3 81.6 50.8 2.769 45.263 3.275 205.7 482.3 39.9 62.1 50.8 3.175 44.45 3.725 233.7 482.3 46.1 72.3 50.8 3.404 43.993 3.975 249.4 482.3 49.6 77.9 50.8 3.962 42.875 4.572 287 482.3 57.9 92.1 50.8 4.775 41.250 5.414 340 482.3 70.3 113.1 50.8 5.516 40.488 5.798 363.9 482.3 75.6 123.1 50.8 2.769 45.263 3.275 235 591.2 45.8 69.9 50.8 3.17...
