Title (EN) MULTIMODAL TOOL JAR
(FR) BATTAGE D'OUTILS MULTIMODAL
Abstract:
(EN) Methods and apparatus for alleviating a stuck condition of a tool string, including using a jarring assembly to collide a plurality of impact surfaces together. The collision results in at least a shock wave inducing i) translational motion along the longitudinal axis of the tool string, and ii) motion in at least one other degree of freedom sufficient to alleviate the stuck condition of the tool string, which may be at least one of: i) translational motion along an axis substantially normal to the longitudinal axis, and ii) rotational motion. Methods may include generating at least one test impact load using a jarring assembly; generating movement information from a sensor responsive to the at least one test impact load; and generating further impact loads using the jarring assembly in dependence upon the movement information.
(FR) L'invention concerne des procédés et un appareil permettant de soulager un état bloqué d'un train d'outils, comprenant l'utilisation d'un ensemble de battage pour faire entrer en collision une pluralité de surfaces d'impact les unes avec les autres. La collision aboutit à au moins une onde de choc provoquant i) un mouvement de translation le long de l'axe longitudinal du train d'outils et ii) un mouvement dans au moins un autre degré de liberté suffisant pour soulager l'état bloqué du train d'outils, qui peut être : i) un mouvement de translation le long d'un axe pratiquement perpendiculaire à l'axe longitudinal et/ou ii) un mouvement de rotation. Les procédés peuvent comprendre la production d'au moins une charge d'impact d'essai à l'aide d'un ensemble de battage ; la production d'informations de déplacement provenant d'un capteur en réponse à ladite ou auxdites charges d'impact d'essai ; et la production d'autres charges d'impact à l'aide de l'ensemble de battage en fonction des informations de déplacement.
