FIELD: oil production; applicable in determination of intervals of fluid flow in annular space of injection well. SUBSTANCE: method includes determination of fluid flow in annular space of injection well by registration of series of thermograms along its wellbore. Series of thermograms is registered in time interval of 4 < t < 40 min upon completion of injection with sealed wellhead. Interval of fluid flow is detected by slowed down rate of temperature recovery in well-formation system. EFFECT: higher accuracy of determination of interval of annular space overflow upward and/or downward from interval of flow string perforation. 1 dwg
