Abstract
Des techniques et un appareil de calcul de contraintes pour des systèmes de pompage de tige de pompage. Un procédé permet de déterminer une contrainte le long dun train de tiges de pompage disposé dans un puits de forage. Le procédé consiste généralement à recevoir, à un processeur, des données de déplacement de tige et de charge de tige mesurées pour le train de tiges de pompage, ce dernier comprenant une pluralité de sections, et à calculer des valeurs de contrainte à une pluralité de nuds de différence finie pour au moins une de la pluralité de sections en fonction, au moins en partie, du déplacement des données de déplacement de tige et de charge de tige mesurées.
