(FR) APPAREIL ET PROCÉDÉ DE SURVEILLANCE D'UNE POMPE AUXILIAIRE
Abstract: front page image
(EN)A method for operating rod pumping unit (100) for a wellbore includes measuring a parameter of the rod pumping unit at a first location (110); measuring the parameter of the rod pumping unit at a second location (160); and subtracting the measured parameters at the second location from the measured parameter at the first location.
(FR)L'invention concerne un procédé d'actionnement d'une pompe auxiliaire (100) pour puits de forage, qui consiste à mesurer un paramètre de la pompe auxiliaire au niveau d'un premier emplacement (110); à mesurer le paramètre de la pompe auxiliaire au niveau d'un second emplacement (160); et à soustraire les paramètres mesurés au second emplacement des paramètre mesurés au premier emplacement.
