Construction and simulation results in different packing stages.
| | Model calculation results | Sand control construction results | Error and remarks |
| When starting to add sand, the wellhead pump pressure (psi) | 670.95 | 697 | | α-Wave packing start pressure (psi) | 528.3456 | 501 | | α-Wave packing average pressure (psi) | 542.346 | 525 | | β-Wave packing average pressure (psi) | 567.1467 | 580 | | Pressure before screenout (psi) | 812.75 | 940 | The simulation calculation considers 100% packing, but the actual construction reaches 138%, which leads to some errors | Compared with the wellhead pump pressure curve, it can be seen that the simulation results have high accuracy and can meet the requirements |
