Summary:A method of cementing a tubular string in a wellbore includes: deploying the tubular string into the wellbore; pumping cement slurry into the tubular string; launching a cementing plug after pumping the cement slurry; propelling the cementing plug through the tubular string, thereby pumping the cement slurry through the tubular string and into an annulus formed between the tubular string and the wellbore; and controlling flow of fluid displaced from the wellbore by the cement slurry to control pressure of the annulus. Une méthode de cimentation dune colonne tubulaire dans des puits de forage comprend : le déploiement de la colonne tubulaire dans le puits de forage; le pompage du laitier de ciment dans la colonne tubulaire; le lancement du bouchon de cimentation après le pompage du laitier de ciment; la propulsion du bouchon de cimentation dans la colonne tubulaire, pompant ainsi le laitier de ciment dans la colonne tubulaire et dans lespace annulaire formé entre la colonne tubulaire et le puits de forage; et la régulation du débit de fluide déplacé du puits de forage par le laitier de ciment pour réguler la pression de lespace annulaire.
