Title (EN) SYSTEM AND METHOD FOR OBTAINING AN EFFECTIVE BULK MODULUS OF A MANAGED PRESSURE DRILLING SYSTEM
(FR) SYSTÈME ET PROCÉDÉ PERMETTANT D'OBTENIR UN MODULE DE COMPRESSIBILITÉ EFFECTIF D'UN SYSTÈME DE FORAGE SOUS PRESSION CONTRÔLÉE
Abstract:
(EN) A method of obtaining an effective bulk modulus of a managed pressure drilling system 1, the method comprising: generating a pressure wave in the system 1; measuring the time interval for the pressure wave to travel over a distance in the system 1; and calculating the effective bulk modulus of the system 1 using the time interval and the length.
(FR) L'invention concerne un procédé permettant d'obtenir un module de compressibilité effectif d'un système de forage sous pression contrôlée (1). Ce procédé consiste : à générer une onde de pression dans le système (1); à mesurer l'intervalle de temps que met l'onde de pression pour se déplacer sur une distance dans le système (1); et à calculer le module de compressibilité effectif du système (1) au moyen de l'intervalle de temps et de la longueur.
