Title (EN) SYSTEM AND METHOD FOR MEASURING WELL FLOW RATE
(FR) SYSTÈME ET PROCÉDÉ DE MESURE DE DÉBIT DE PUITS
Abstract:
(EN) The present invention discloses an improved system for measurement of the liquid flow rate and totalized liquid production of a producing well. In the method of the present invention, liquid production rate in a pumping well is determined by calculation based upon wellbore geometry and continuously monitoring the depth of the fluid level within the wellbore. It is applicable to any pump lifted well where it is possible to shut the pump off periodically. Accuracy is enhanced with this method by properly accounting for pump leakage and where pump leakage is either known or can be estimated within reasonable limits or where it is measured during the pump shut off cycle.
(FR) La présente invention concerne un système amélioré de mesure du débit de liquide et de la production de liquide totalisée d'un puits de production. Dans le procédé selon la présente invention, un taux de production de liquide dans un puits de pompage est déterminé à l'aide d'un calcul sur la base d'une géométrie du puits de forage et en contrôlant de façon continue la profondeur du niveau de fluide à l'intérieur du puits de forage. Celui-ci est applicable à un quelconque puits à pompe permettant de fermer périodiquement la pompe. La précision est améliorée grâce au présent procédé grâce à une prise en compte adéquate de la fuite de pompe lorsqu'une fuite de pompe est connue ou peut être estimée dans des limites raisonnables ou lorsque celle-ci est mesurée pendant le cycle de fermeture de la pompe.
