초록 ▼

A duct-forming device is disclosed for use in a well completion apparatus of the kind, wherein a bore hole casing is positioned in a bore hole and duct-forming devices of alkali- and acid-resistant metal－such as steel－are secured at spaced levels to the casing in alignment with holes machined in the casing wall. In accordance with the invention, a closure device is arranged within the duct-forming device which permits flow of predetermined amounts of liquid, such as acid, from the interior of the casing through the duct-forming device and into the producing formation, while gradually being moved by the liquid into a position in which such fluid flow is prevented. After the fluid flow has been stopped by the closure device and when the formation pressure exceeds the pressure within the duct-forming device and the casing, fluid from the formation then forces the closure device toward and into the casing space to permit thereafter free flow of formation fluid into the duct-forming device and the casing or of pressurized treatment liquid from the casing into the formation. The inventive arrangement permits inter alia the establishment of a sufficient and substantially uniform feeding rate of treatment liquid, such as acid, from the casing into the producing formation through all the duct-formers in preparation for subsequent acidification or other treatments, such as sand fracking.

A duct-forming device for use in well completion apparatus of the kind, wherein a bore hole casing is positioned in a bore hole and duct-forming devices of acid-resistant metal are secured at spaced levels of the casing in alignment with holes machined in the casing wall, and wherein, upon pressurizing the casing space, each duct-forming device is laterally extended from the casing for making contact with a producing formation, each of said duct-forming device comprising: (a) a terminal sleeve adapted to make contact with the producing formation when the duct-forming device has been laterally extended, said terminal sleeve having passageway means for establishing communication between said formation and the interior space of said duct-forming device; (b) a passage-forming removable piston assembly within said interior space of the duct-forming device and including means defining passages through said piston assembly and a piston means movable between I. an initial position in which the piston means permits fluid flow through the passageway means of (a); II. a blocking position in which said piston means blocks fluid flow through said passageway means of (a); and III. an ultimate position in which the piston means and the entire piston assembly are forced from the interior space of said duct-forming device toward and into the casing space; (c) an acid and/or alkali-soluble closure cap having hole means, said closure cap being mounted on said duct-forming device adjacent the end at which the duct-forming device is secured to said casing; and (d) an acid and/or alkali-soluble flow-impeding means located within the interior of said duct-forming device and being interpositioned between said closure cap (c) and said piston assembly (b), whereby acidic or alkaline liquid forced down said casing space impinges on and dissolves that closure cap, while simultaneously passing through said hole means of said closure cap to make contact with and dissolve said flow-impeding means, said liquid, after having eaten through said flow-impeding means flowing through the passages of said piston assembly and through the passageway means in said terminal sleeve into said formation while, depending on its flow rate and its pressure, said liquid gradually moves said piston means of said piston assembly from said initial position (I) into said blocking position (II) to block the communication between the formation and the interior of said duct-forming device, and after said liquid has substantially totally dissolved said flow-impeding means and said closure cap and the formation pressure exceeds the pressure within the interior of said duct-forming device, fluid from said formation forces said piston assembly, including the piston means, towards and into said casing space, said means defining passages through said piston assembly being configured to permit flow from one side of said piston to the opposite side thereof through said terminal sleeve (a) in a direction from said casing toward said formation when said flow-impeding means has been dissolved and when said piston means is in said initial position (I), said piston means including blocking means for blocking flow through said passageway means when said piston means is in said blocking position (II).
