Abstract
Cette invention décrit un appareil qui émet des impulsions de pression dans le coulis de ciment d'un puits, au moment où le coulis passe de la forme liquide à la forme solide, dans le but d'améliorer la qualité du béton. De façon plus précise, l'invention vise à éviter la migration des gaz, à déterminer le temps de prise et à améliorer la qualité des registres d'évaluation du ciment.
