Title (EN) ELECTRICAL CABLES WITH STRANDED WIRE STRENGTH MEMBERS
(FR) CABLES ELECTRIQUES POURVUS D'ELEMENTS DE RENFORT A FILS TORONNES
Abstract:
(EN) Disclosed are high strength wellbore electric cables, which are formed from a plurality of strength members. The strength members are formed from several stranded filament wires which may be encased within a jacket of polymeric material. The strength members may be used as a central strength member, or even layered around a central axially positioned component or strength member, to form a layer of strength members. Cables of the invention may be of any practical design, including monocables, coaxial cables, quadcables, heptacables, slickline cables, multi-line cables, etc., and have improved resistant to corrosion, torque balancing, and gas migration from a wellbore to the surface.
(FR) L'invention concerne des câbles électriques haute résistance pour des puits de forage, formés par une pluralité d'éléments de renfort. Ces éléments de renfort sont formés par plusieurs fils toronnés qui peuvent être enrobés par une gaine en matériau polymère. Les éléments de renfort peuvent faire office d'élément de renfort central, ou être disposés en couches autour d'un composant ou élément de renfort central positionné de manière axiale, afin que soit formée une couche d'éléments de renfort. Les câbles de l'invention peuvent être des câbles de conception pratique quelconque, de type monocâbles, câbles coaxiaux, câble à quartes en étoile, câbles à sept conducteurs, câbles lisses, câbles multilignes, etc., et présentent des propriétés améliorées en matière de résistance à la corrosion, d'équilibrage de couple, et de migration de gaz d'un puits de forage à la surface.
