발명의 명칭: (EN) SYSTEMS AND METHODS FOR MEASURING THE POSITIONS OF FLUIDS IN A WELL
(FR) SYSTÈMES ET PROCÉDÉS POUR MESURER LES POSITIONS DE FLUIDES DANS UN PUITS
요약서:
(EN) A method for cementing a borehole includes pumping a collection of fluids into the borehole through a tubular string in the borehole, flowing the collection of fluids up an annulus positioned between the tubular string and a sidewall of the borehole, monitoring a volume of the fluids pumped into the borehole, performing a first estimation of a position of the fluids based on the volume of the collection of fluids pumped into the borehole, and an initial estimate of an average diameter of the sidewall of at least a portion of the borehole, calculating a corrected estimate of the average diameter based on the first estimation and a pressure of the fluids measured at an inlet of the tubular string, and performing a second estimation of the position of the fluids based on the volume of the fluids pumped into the borehole and the corrected estimate of the average diameter.
(FR) L'invention concerne un procédé de cimentation d'un trou de forage qui comprend le pompage d'un prélèvement de fluides dans le trou de forage à travers une trame tubulaire dans le trou de forage, l'écoulement du prélèvement de fluides vers le haut jusqu'à un espace annulaire situé entre la trame tubulaire et une paroi latérale du trou de forage, la surveillance d'un volume des fluides pompés dans le trou de forage, la réalisation d'une première estimation d'une position des fluides basée sur le volume du prélèvement de fluides pompés dans le trou de forage, et une estimation initiale d'un diamètre moyen de la paroi latérale d'au moins une partie du trou de forage, le calcul d'une estimation corrigée du diamètre moyen basé sur la première estimation et une pression des fluides mesurés au niveau d'une entrée de la trame tubulaire, et la réalisation d'une seconde estimation de la position des fluides basée sur le volume des fluides pompés dans le trou de forage et de l'estimation corrigée du diamètre moyen.
