Coalbed Methane Production System Simulation and Deliverability Forecasting: Coupled Surface Network/Wellbore/Reservoir Calculation
Table 1
Comparison of the four models.
| Calculation method | Application | Calculation accuracy | Advantages/disadvantages |
| Model 1 | GCF > 0.3 | Relatively high | High precision, but large amount of calculation, narrow application scope | Model 2 | All cases | Relatively high | Simple calculation process, high precision, good stability | Model 3 | All cases | Change with the gas well conditions | Complex calculation process, poor stability | Model 4 | All cases | Change with the gas well conditions | Large amount of calculation, poor stability |
