Title (EN) IMPROVEMENTS IN DELIVERING PRESSURISED FLUID
(FR) AMÉLIORATIONS APPORTÉES À LA DISTRIBUTION D'UN FLUIDE SOUS PRESSION
Abstract:
(EN) A pressure intensifier (10) and method of increasing fluid pressure at a desired location in a well bore. A central mandrel (22) having a bore (26) therethough is affixed in a string. Surrounding the mandrel is a cylindrical body (18) having stacked pistons (40a, 40b, 40c). At a predetermined fluid pressure through the bore, the pistons release and are moved downwards, to integrate pressure across the pistons and act on a chamber (20c) pre-filled with application fluid. The application fluid is forced through delivery conduits (52) at a higher pressure than the predetermined fluid pressure and may be used to morph a tubular. In an embodiment, the predetermined fluid pressure is field adjustable.
(FR) La présente invention concerne un multiplicateur de pression (10) et un procédé d'augmentation de la pression d'un fluide à un emplacement souhaité dans un puits de forage. Un mandrin central (22) traversé par un alésage (26) est fixé dans une chaîne. Un corps cylindrique (18) ayant des pistons empilés (40a, 40b, 40c) entoure le mandrin. À une pression de fluide prédéterminée à travers l'alésage, les pistons se relâchent et sont déplacés vers le bas, afin d'intégrer une pression dans ces derniers et agir sur une chambre (20c) pré-remplie d'un fluide d'application. Le fluide d'application est poussé à travers des conduits de distribution (52) à une pression supérieure à la pression de fluide prédéterminée et peut être utilisé pour former un matériel tubulaire. Dans un mode de réalisation, la pression de fluide prédéterminée est réglable sur place.
