Construction and simulation results in different packing stages.

Model calculation resultsSand control construction resultsError and remarks

When starting to add sand, the wellhead pump pressure (psi)670.95697
α-Wave packing start pressure (psi)528.3456501
α-Wave packing average pressure (psi)542.346525
β-Wave packing average pressure (psi)567.1467580
Pressure before screenout (psi)812.75940The 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
