Fluid diversion measurement systems and methods are described. One method includes inserting a tubular tubing having one more fluid injection ports into a wellbore, injecting a treatment fluid through the injection port, and determining differential flow of the treatment fluid based on measuring the concentration of at least one particular component of a wellbore fluid located in the annulus formed between the wellbore and tubular; and means for using the measured parameters in realtime to monitor, control, or both monitor and control diversion of the fluid.
La présente invention se rapporte à des systèmes et à des procédés de mesure de la dérivation d'un fluide. Un procédé selon l'invention consiste : à introduire dans un puits de forage un tuyau tubulaire possédant un ou plusieurs orifices d'injection de fluide; à injecter un fluide de traitement à travers le ou les orifices d'injection; et à déterminer l'écoulement différentiel du fluide de traitement, par la mesure de la concentration d'au moins un composant particulier d'un fluide de forage situé dans l'annulaire formé entre le puits de forage et le tube de production tubulaire. Les systèmes selon l'invention comprennent des moyens destinés à utiliser les paramètres utilisés en temps réel pour contrôler et/ou commander la dérivation du fluide.
