VIRTUAL FLOWMETER FOR A WELL

A technique includes inducing a distributed temperature change along a portion of a wellbore and measuring a time varying temperature along the portion of the wellbore due to the induced change. The technique includes determining a distributed flow rate in the portion based at least in part on the m...

description A technique includes inducing a distributed temperature change along a portion of a wellbore and measuring a time varying temperature along the portion of the wellbore due to the induced change. The technique includes determining a distributed flow rate in the portion based at least in part on the measured time varying temperature before the temperature reaches equilibrium. L'invention concerne une technique comprenant l'induction d'un changement de température réparti le long d'une partie d'un forage et la mesure d'une température variant au cours du temps le long de la partie du forage en raison du changement induit. La technique comprend la détermination d'un débit réparti dans la partie en se basant au moins partiellement sur la température variant au cours du temps qui est mesurée avant que la température atteigne un équilibre.
