Title
(EN) SYSTEMS AND METHODS FOR MEASURING MULTIPHASE FLOW IN A HYDROCARBON TRANSPORTING PIPELINE
(FR) SYSTEMES ET PROCEDES DE MESURE D'UN ECOULEMENT POLYPHASIQUE DANS UN PIPELINE DE TRANSPORT D'HYDROCARBURES
Abstract
(EN)
This disclosure relates in general to methods and systems for measuring multiphase flows in a pipeline using a combination of venturi, microwave and radiation techniques, where the pipeline is configured to transport hydrocarbons. More specifically, but not by way of limitation, certain embodiments of the present invention provide methods and systems in which low activity radiation sources may be used in combination with one or more microwave transmitter-receiver pairs and pressure differential sensors to measure the flow rates and fractions of phases in multiphase flows in a pipeline, such as may be encountered in producing hydrocarbon wells. Additionally, other embodiments of the present invention provide for the arrangement of one or more microwave transmitter-receiver pairs, one or more radiation source-detector pairs and/or one or more pressure sensor ports in the same cross-section of the throat of a venturi to measure multiphase flow in a hydrocarbon transporting pipeline.

Cette invention porte, en général, sur des procédés et sur des systèmes de mesure d'écoulements polyphasiques dans un pipeline, ces procédés et systèmes utilisant une combinaison de techniques du venturi, en hyperfréquence et de rayonnement, le pipeline étant configuré pour transporter des hydrocarbures. De manière plus spécifique, mais pas exclusivement, certaines réalisations de cette invention concernent des procédés et des systèmes dans lesquels il est possible d'utiliser des sources de rayonnement à faible activité en combinaison avec une ou plusieurs paires d'émetteurs-récepteurs en hyperfréquence et de capteurs à pression différentielle pour mesurer les débits et les fractions de phases dans les écoulements polyphasiques d'un pipeline, tels que ceux que l'on peut trouver dans la production des puits d'hydrocarbure. Selon d'autres réalisations, l'invention porte également sur l'agencement d'une ou plusieurs paires d'émetteurs-récepteurs en hyperfréquence, d'une ou plusieurs paires de détecteurs de source de rayonnement et/ou d'un ou plusieurs ports de capteurs de pression dans la même section transversale du col d'un venturi pour mesurer l'écoulement polyphasique dans un pipeline de transport d'hydrocarbure.
