Abstract
Apparatus for the completion of wells of the kind in which a well-hole casing is adapted to be positioned in a borehole and an acid-resistant metal duct forming device is secured to the casing in alignment with an orifice machined in the wall of the intubation, said duct forming device being capable of being deployed laterally from the tubing to make contact with a productive formation, characterized in that the duct-forming device includes a terminal sleeve that is blocked and closed by a metal plug soluble in acid that at the introduction of the acid in the sleeve is at least partially dissolved to become dislodged from its corresponding sleeve, and in that a safety cap is secured to that end of the duct forming device closest to the tubing, being said safety cap substantially in alignment with the wall of the body; baciºn and located substantially within said mechanized orifice of the intubation and with a narrow passage controlled by a valve that allows the flow of fluid from the interior of the intubation towards the said plug but prevents the flow of fluid through the sleeve and into the interior of the intubation, said safety cap being at least partially constructed of an acid-soluble metal.
