A well bore servicing apparatus comprising a housing having a longitudinal axis and a through bore, and a movable member disposed in said housing, said movable member having a through bore and a fluid aperture therein, wherein said movable member is movable between a first stop position and a second stop position relative to said housing and along said axis, wherein said fluid aperture is in fluid communication with said housing through bore and said movable member through bore to provide a fluid stream to the well bore in said first and second axially spaced stop positions. A well bore servicing apparatus comprising a work string, a housing coupled to said work string, and a member slidably coupled to said housing, said slidable member having a fluid jetting nozzle and a fluid path therethrough communicating fluid to said fluid jetting nozzle, wherein said slidable member is operable to place said fluid jetting nozzle in a plurality of axially spaced stop positions relative to said housing and said work string.
L'invention porte sur un appareil d'entretien de puits de forage qui comporte un boîtier ayant un axe longitudinal et un passage traversant, et un élément mobile disposé dans ledit boîtier, ledit élément mobile dans lequel sont formés un passage traversant et une ouverture de fluide, ledit élément mobile pouvant se déplacer entre une première position d'arrêt et une deuxième position d'arrêt par rapport au dit boîtier et le long dudit axe, ladite ouverture de fluide étant en communication de fluide avec ledit passage traversant de boîtier et ledit trou traversant de l'élément mobile de façon à injecter un flux de fluide dans le puits de forage dans lesdites première et deuxième positions d'arrêt axialement espacées. L'invention porte également sur un appareil d'entretien de puits de forage comportant un train de tiges, un boîtier couplé audit train de tiges et un élément couplé de façon coulissante audit boîtier, ledit élément coulissant possédant une buse de projection de fluide et un trajet de fluide traversant fournissant un fluide à ladite buse d'éjection de fluide, ledit élément coulissant fonctionnant de façon à disposer ladite buse d'éjection de fluide dans une pluralité de positions d'arrêt axialement espacées par rapport audit boîtier et audit train de tiges.
