| Abstract | Geothermal wells completed with multi-feed zones may experience unstable production characteristics such as oscillations of wellhead pressure and discharge rate. Unsteady state steam-water two-phase flow in wellbore was numerically analyzed for examining the effects of low temperature water inflow probably due to quick return of reinjected water to production wells. Simulated results showed that depths of flashing point are affected by a degree of inflow of low temperature fluid from shallow feed zone. |
