To perform a cleanout operation in a wellbore, a cleaning tool having a coiled tubing and an electrical pump assembly is run into the wellbore. The electrical pump assembly that is located in the wellbore is activated. In response to fluid flow generated by the electrical pump assembly, removal of debris from the wellbore is caused by directing fluid containing the debris into the coiled tubing for delivery to an earth surface.
La présente invention concerne un outil de nettoyage comportant une colonne de production enroulée et un ensemble de pompe électrique déployé pour effectuer une opération dans un trou de forage. L'ensemble de pompe électrique qui est situé dans le trou de forage est activé. En réaction à un écoulement de fluide généré par l'ensemble de pompe électrique, l'élimination de débris depuis le trou de forage est entraînée en dirigeant le fluide contenant les débris dans la colonne de production enroulée pour être évacué vers une surface terrestre.
