Title
(EN) DRILL BIT VALVE
(FR) VANNE DE TRÉPAN
Abstract
(EN)
An example drill bit (1) includes a body (10) that is connectable to a drill string (2). The body (10) has a base (7) configured to face downhole within a wellbore (5) and a perimeter (6) configured to face a wall (8) of the wellbore (5). The body (10) includes a first nozzle (14) and a second nozzle (14). The first nozzle corresponds to a first channel (12) that exits the body (10) through the perimeter (6) and the second nozzle (14) corresponds to a second channel (13) that exits the body through the base (7). The example drill bit (1) also includes a bit cutter (11) on the base (7) of the body (10) and a valve (16) within the body (10). The valve (16) is configured to move within the body to block either the first channel (12) or the second channel (13).
(FR)
L'invention concerne un trépan (1) dont un exemple de réalisation comprend un corps (10) qui peut être relié à un train de tiges de forage (2). Le corps (10) comprend une base (7) configurée pour être tournée vers le fond de trou à l'intérieur d'un puits de forage (5) et un périmètre (6) configuré pour faire face à une paroi (8) du puits de forage (5). Le corps (10) comprend une première buse (14) et une deuxième buse (14). La première buse correspond à un premier canal (12) qui sort du corps (10) à travers le périmètre (6), et la deuxième buse (14) correspond à un deuxième canal (13) qui sort du corps à travers la base (7). L'exemple de trépan (1) comprend également un dispositif de coupe de trépan (11) sur la base (7) du corps (10) et une vanne (16) à l'intérieur du corps (10). La vanne (16) est configurée pour se déplacer à l'intérieur du corps pour bloquer soit le premier canal (12) soit le deuxième canal (13).
