Failure Analysis of Tubing Collapse in a Gas Well
Table 7
Stress load comparison results of simulated collapse test and failed tubing in the well.
| Sample | Axial load (kN) | External pressure (MPa) | Results | Remarks |
| The same batch of tubing | 1,146 | 52.5 | The pipe body was collapsed | There are slight differences in the performance of the same batch of tubing, which can be ignored | Failed tubing in the well | 1,146 | 52.3 | The pipe body was collapsed |
