Abstract

Un élément d'ancrage (A) est fixé à l'intérieur d'un forage de puits tubé par un dispositif de fixation (T) muni d'un loquet (10) qui fixe cet élément (A) de façon réversible. Le sifflet de déviation (27) comporte des surfaces (33) en prise avec les surfaces d'un arbre (32) à la surface du sol pour orienter le sifflet de déviation de manière à le placer dans une direction voulue. Le sifflet de déviation (27) est ensuite descendu dans un forage de puits tubé et fixé de manière réversible à l'élément d'ancrage (A) par un loquet (35) qui vient s'engager dans un évidement (3) de l'élément d'ancrage et est fixé de façon à prévenir toute rotation par une surface (31d) engagée dans la surface de fixation (8) du sifflet de déviation ménagée dans l'élément d'ancrage (A). Un forage de puits latéral peut alors être foré depuis le forage de puits tubé dans la direction et à la cote voulues. Le sifflet de déviation (27) peut être relié à un train de tiges de forage (DS) à des fins de descente à l'intérieur de l'élément d'ancrage (A) placé dans le forage. Si on le souhaite, un tubage de puits ordinaire (53) muni d'un dispositif de fixation (77) coopère avec le dispositif de fixation (78) du sifflet de déviation (27) pour retirer le sifflet de l'élément d'ancrage (A) ou pour placer le sifflet dans la position voulue dans celui-ci.
