Title (EN) PRESSURE EXCHANGER WEAR PREVENTION
(FR) PRÉVENTION DE L'USURE D'UN ÉCHANGEUR DE PRESSION
Abstract:
(EN) Apparatus and methods for pressurizing well operations fluids via a pressure exchanger. The pressure exchanger has a housing, a rotor within the housing, a first cap covering the rotor at a first end of the housing, and a second cap covering the rotor at a second end of the housing. The rotor includes chambers distributed around a central axis of the rotor and a first fluid passage. Each of the chambers and the first fluid passage extend through the rotor between a first face of the rotor and a second face of the rotor. The first cap includes a first fluid inlet, a first fluid outlet, and a second fluid passage, and the second cap includes a second fluid inlet and a second fluid outlet. The second fluid passage fluidly connects the first fluid passage with the first fluid outlet.
(FR) L'invention concerne un appareil et des procédés de pressurisation de fluides d'opérations dans un puits par l'intermédiaire d'un échangeur de pression. L'échangeur de pression comprend un boîtier, un rotor à l'intérieur du boîtier, un premier capuchon recouvrant le rotor au niveau d'une première extrémité du boîtier et un second capuchon recouvrant le rotor au niveau d'une seconde extrémité du boîtier. Le rotor comprend des chambres réparties autour d'un axe central du rotor et un premier passage de fluide. Chacune des chambres et le premier passage de fluide s'étendent à travers le rotor entre une première surface du rotor et une seconde surface du rotor. Le premier capuchon comporte une première entrée de fluide, une première sortie de fluide et un second passage de fluide. Le second capuchon comporte une seconde entrée de fluide et une seconde sortie de fluide. Le second passage de fluide relie de manière fluidique le premier passage de fluide à la première sortie de fluide.
