This invention describes an apparatus to provide pressure pulses to cement slurries in a well, as the cement makes the transition from liquid slurry to a solid, with the objective to improve the quality of the cement. More specifically, to prevent gas migration, determine the waiting-on-cement time and improve the quality of cement evaluation logs.
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.
