Numerical study on the effects of wellhead restriction modes on the transient behaviors of a geothermal well deliverability applicable for short period of measurement

The transient behaviors of fluid, particularly on the stabilization time for a short period of artificial production test to establish deliverability curve is investigated numerically. Based on the experiences, the measured parameters, i.e. wellhead pressure and mass flow rate are taken when they are judged to be in stable condition. However, duration required for these variables to stabilize depends on flowing behavior of steam-water two-phase...
