Title
(EN) DOWNHOLE HYDRAULIC JETTING ASSEMBLY
(FR) ENSEMBLE DE NETTOYAGE AU JET HYDRAULIQUE DE FOND DE TROU
Abstract
(EN)
A downhole hydraulic jetting assembly is provided herein. The assembly is useful for steerably jetting multiple lateral boreholes into a subsurface formation from an existing parent wellbore of any inclination. The assembly is useful for single trip completions or recompletion through the placement of multiple lateral boreholes. The assembly includes an external system wherein coiled tubing and a whipstock member are run into a wellbore. The assembly further includes an internal system that is run into the wellbore housed within the external system, but which allows a nozzle at the end of the hose to be directed against a wellbore exit location after the whipstock member is located and set. A window may be formed through casing using the jetting hose and nozzle, followed by the formation of a lateral bore hole. The whipstock may be re-located and/or re-oriented for the jetting of additional casing exits and lateral boreholes in the same trip.
(FR)
La présente invention concerne un ensemble de nettoyage au jet hydraulique de fond de trou. L'ensemble est utile pour nettoyer au jet, de manière orientable, de multiples trous de forage latéraux dans une formation souterraine à partir d'un puits de forage parent existant d'inclinaison quelconque. L'ensemble est utile pour des complétions de manœuvre uniques ou une remise en production par l'intermédiaire du placement de multiples trous de forage latéraux. L'ensemble comprend un système externe dans lequel un tube spiralé et un élément de sifflet déviateur passent dans un puits de forage. L'ensemble comprend en outre un système interne qui passe dans le puits de forage logé à l'intérieur du système externe, mais qui permet à une buse au niveau de l'extrémité du tuyau souple d'être dirigée contre un emplacement de sortie de puits de forage, après que l'élément de sifflet déviateur est localisé et installé. Une fenêtre peut être formée à travers un boîtier à l'aide du tuyau souple et de la buse de nettoyage au jet, suivie par la formation d'un trou d'alésage latéral. Le sifflet déviateur peut être re-localisé et/ou ré-orienté pour le nettoyage au jet de sorties de boîtier et de trous de forage latéraux supplémentaires dans la même manœuvre.
