Abstract

Un dispositivo para perforar una ventana en una tubería de revestimiento de un pozo de sondeo formado en una formacion terrestre. El sistema comprende unafresadora para perforar dicha ventana, un dispositivo de guía para guiar la fresadora a lolargo de un trayecto seleccionado dentro de la tuberíade revestimiento durante la perforacion de dicha ventana, y el dispositivo de guía presenta medios para disponer fijamente el dispositivo de guía dentrode la tubería de revestimiento. Eldispositivo de guía está provisto con medios de empuje para impulsar la fresadora a lo largo de la trayectoriaseleccionada durante la perforacion de la ventana.A device for drilling a window in a casing pipe of a borehole formed in a land formation. The system comprises a drilling machine for drilling said window, a guiding device for guiding the milling machine along a selected path within the casing pipe during the perforation of said window, and the guiding device presents means for fixedly arranging the guiding device within the casing pipe. The guide device is provided with pushing means to drive the mill along the path selected during the drilling of the window.
