Title (EN) INTERNAL TUBING CUTTER
(FR) ORGANE DE COUPE DE TUBAGE INTERNE
Abstract: front page image
(EN) Implementations of the present invention include an internal tubing cutter including ramp surface(s) and roller that cause cutters to move linearly between retracted and deployed positions. The linear actuation of the cutters can allow for more robust cutting and increased cutting efficiency. Implementations of the present invention also include cutting systems including an internal tubing cutter, and methods of cutting tubular members, such as borehole casings and drill strings, using such drilling systems.
(FR) Des mises en œuvre de la présente invention comprennent un organe de coupe de tubage interne comprenant une ou des surface(s) de rampe et un rouleau qui fait en sorte que les organes de coupe se déplacent linéairement entre des positions rétractée et déployée. L'actionnement linéaire des organes de coupe peut permettre une coupe plus robuste et une efficacité de coupe accrue. Des mises en œuvre de la présente invention comprennent également des systèmes de coupe comprenant un organe de coupe de tubage interne, et des procédés de découpe de membres tubulaires, tels que des cuvelages de trou de forage et des trains de tiges, utilisant de tels systèmes de forage.
