Title (EN) HYBRID DRIVE SYSTEMS FOR WELL STIMULATION OPERATIONS
(FR) SYSTÈMES DE MOTORISATION HYBRIDE POUR OPÉRATIONS DE STIMULATION DE PUITS
Abstract:
(EN) In accordance with presently disclosed embodiments, a hybrid drive system that uses multiple sources of mechanical energy to drive a pump is provided. The hybrid drive system may include a first mover for generating first mechanical energy, a pump, a drivetrain for providing first mechanical energy from the first mover to the pump, and a second mover within the drivetrain to generate and provide second mechanical energy to the pump. The multiple sources of mechanical energy may provide flexibility with respect to system design and allow for alternative sources of fuel and energy to be used to drive pumping systems. This may reduce the total diesel fuel consumption necessary to perform a well stimulation operation as well as provide for configurations in which diesel engines may be excluded from the pumping process in favor of alternative energy sources that typically do not have sufficient torque capacity to power a pump.
(FR) Selon les modes de réalisation, la présente invention concerne un système de motorisation hybride qui utilise des multiples sources d'énergie mécanique pour entraîner une pompe. Le système de motorisation hybride peut comprendre : un premier moteur, pour générer une première énergie mécanique ; une pompe ; une chaîne cinématique, pour fournir une première énergie mécanique du premier moteur à la pompe ; et un deuxième moteur, à l'intérieur de la chaîne cinématique, pour générer et pour fournir une deuxième énergie mécanique à la pompe. Les multiples sources d'énergie mécanique peuvent fournir une flexibilité en ce qui concerne la conception du système et permettre d'utiliser des sources alternatives de combustible et d'énergie pour entraîner des systèmes de pompage. Ceci peut réduire la consommation totale de carburant diesel, nécessaire pour effectuer une opération de stimulation de puits ainsi que fournir des configurations permettant de s’affranchir des moteurs diesel dans le processus de pompage, et d'utiliser à leur place des sources d'énergie alternatives qui ne présentent typiquement pas de capacité de couple suffisante pour alimenter une pompe.
