Title
(EN) FRAC PLUG WITH COLLAPSIBLE PLUG BODY HAVING INTEGRAL WEDGE AND SLIP ELEMENTS
(FR) BOUCHON DE FRACTURATION AVEC CORPS DE BOUCHON PLIABLE AYANT DES ÉLÉMENTS DE COIN ET DE GLISSEMENT INTÉGRÉS
Abstract
(EN) A frac plug apparatus has a plug body that comprises a central bore and separable elements. The central bore extends axially through the plug body. The separable elements are joined by relatively weak bridging portions adapted to break in a controlled manner, the separable elements thereby forming an integral component comprised of the separable elements. The separable elements comprise a wedge element and an array of slip elements. The slip elements are joined to the wedge element by first bridging portions.
(FR) Un appareil de bouchon de fracturation présente un corps de bouchon qui comprend un alésage central et des éléments séparables. L'alésage central s'étend axialement à travers le corps de bouchon. Les éléments séparables sont reliés par des parties de pontage relativement faibles conçues pour se rompre de manière contrôlée, les éléments séparables formant ainsi un composant intégral constitué des éléments séparables. Les éléments séparables comprennent un élément de coin et un réseau d'éléments de glissement. Les éléments de glissement sont reliés à l'élément de coin par des premières parties de pontage.
