Abstract
Cette invention décrit une méthode de formation de trous de forage latéraux dans un puits de forage parent existant. Le puits de forage a été construit avec une chaîne de tubages. La méthode comprend généralement la fourniture d'un outil de fond de puits doté d'un sifflet déviateur. La méthode comprend également la descente de l'ensemble dans le puits de forage parent. Une force est appliquée à l'ensemble, faisant pivoter le sifflet déviateur dans le puits de forage en position de fonctionnement. À cette position, une surface courbée du sifflet déviateur forme un rayon sur le diamètre interne du tubage. Un tuyau de lançage est alimenté dans le puits de forage. Au contact de la surface courbée du sifflet déviateur, le tuyau de lançage est redirigé dans une fenêtre dans le tubage. Un liquide hydraulique est injecté sous pression dans le tuyau pour fournir un lançage hydraulique. Le tuyau est dirigé dans une fenêtre et dans la formation pour créer un trou de forage latéral qui se prolonge pendant de nombreux pieds vers l'extérieur jusqu'à une formation souterraine. Cette invention décrit également un outil destiné à former des trous de forage latéraux à partir d'un puits de forage parent. L'ensemble utilise essentiellement le diamètre interne complet du tubage comme rayon de courbure du tuyau de lançage hydraulique.
