Abstract
Existence of maximum flow-rates of steam-water wells is obtained by numerical modeling. These flow-rates are close to exploitation values. The obtained phenomenon is associated with the first stage of the critical flow. The maximum flow-rates are about half the values determined by the famous James’s formula, which meets the third stage of critical flow. Existence of maximum flow-rates should be taken into account in the forecast of well productivity when exploitation conditions change.
