Beschreibung
Zusammenfassung:	The present disclosure relates to downhole tools and related methods that provide for controlled radial movement of one or more nozzles to provide an adjustable and variable standoff between the exit of the nozzle(s) and the wellbore surface in the treatment zone of a wellbore during matrix acidizing. La présente invention concerne des outils de fond et des procédés associés qui permettent un mouvement radial contrôlé d'une ou plusieurs buses pour ménager un écartement réglable et variable entre la sortie de la ou des buses et la surface du puits de forage dans la zone de traitement d'un puits de forage pendant une acidification de matrice.
