Abstract

Méthode de forage profond et ensemble de forage L’invention concerne une méthode de forage profond comprenant une étape de forage de la roche au niveau d’un front de taille au moyen d’une tête de forage pour creuser un puits (11) présentant une section transversale sensiblement circulaire. La tête de forage creuse le puits selon un profil de taille présentant au moins un enfoncement de telle sorte que le profil présente un écart de profondeur (H) entre la périphérie transversale et chaque enfoncement et le centre (30) du puits afin de relâcher au moins une partie des concentrations de contraintes présentes dans la roche à forer, au moins l’un des enfoncements étant situé sur la périphérie transversale (32). Le rapport entre d’une part la somme des écarts de profondeur (H) entre chaque enfoncement et le centre du puits et d’autre part le rayon (R) de la section transversale étant supérieur à 0,2. Figure pour l'abrégé : Figure 6
