Title (EN) CHEMICAL HEAT SOURCES FOR USE IN DOWN-HOLE OPERATIONS
(FR) SOURCES DE CHALEUR CHIMIQUE DESTINÉES À ÊTRE UTILISÉES DANS DES OPÉRATIONS DE FOND DE TROU
Abstract:
(EN) A chemical reaction heat source for use in heaters for downhole applications is provided. The heat source has a solid fuel composition that comprises thermite and a binding agent. The binding agent serving to maintain the solid form of the solid fuel composition during burning and ensure a predetermined uniform heating pattern can be provided for longer. The solid fuel composition can be provided in the form of blocks. The solid fuel composition can also be provided in the form of a plurality of fragments that, during burning, behave more like powdered thermite and have the ability to flow.
(FR) L'invention concerne une source de chaleur à réaction chimique destinée à être utilisée dans des dispositifs de chauffage pour des applications de fond de trou. La source de chaleur comprend une composition de combustible solide qui comprend de la thermite et un agent liant. L'agent liant servant à maintenir la forme solide de la composition de combustible solide pendant la combustion et à assurer un schéma de chauffage uniforme prédéterminé peut être fourni plus longtemps. La composition de combustible solide peut être fournie sous la forme de blocs. La composition de combustible solide peut également être fournie sous la forme d'une pluralité de fragments qui, pendant la combustion, se comportent plus comme de la thermite en poudre et ont la capacité de s'écouler.
