Abstract

L'invention porte sur un procédé d'élimination des dépôts (22) de sulfates de métaux alcalino-terreux de la surface intérieure de tubes de production (16) de forages consistant à les (22) mettre en contact avec un solvant d'une densité spécifique d'au moins 1,2 tout en les (22) meulant à l'aide d'une meule (20) rotative entraînée par un moteur de forage.
