Definitions

  • the invention relates to a perforating gun with an outer gun barrel inside which is coaxially disposed an inner tube carrying perforators which are ignitable via a detonating cord passing through the cannon barrel and, upon ignition, penetrate the cannon barrel to form bullet holes, means for automatically closing the penetration holes are provided after the shot and this agent is a swellable medium.
  • Perforation guns are used in deep hole blasting in the oil and gas industry, as well as in hydraulic engineering to connect the hole to the storage horizon.
  • the well is usually a wellbore fluid. This can be an introduced liquid or the medium to be pumped from the surrounding rock.
  • a perforation gun consists of an outer cannon tube inside which perforators - usually hollow or projectile charges - are arranged, which shoot when fired radially outward through the gun barrel.
  • perforators - usually hollow or projectile charges - are arranged, which shoot when fired radially outward through the gun barrel.
  • the shaped charges are carried by a thin-walled support tube which extends coaxially inside the gun barrel.
  • CONFIRMATION COPY this agent are cartridges with a swellable 2-component foam. These cartridges are located in the gun barrel and break through the detonated detonating cord, causing foam to escape from the cartridges, swelling and plugging the bullet holes.
  • the invention has for its object to improve a perforation gun according to the preamble of claim 1 so that the swellable medium requires a small space and is easy to integrate into the perforation gun.
  • no additional part to be included in the perforation gun in one embodiment as possible no additional part to be included in the perforation gun.
  • the swellable medium is arranged in a planar manner in the interior of the perforation gun.
  • Flat structures require less space and are easily integrated into the perforation gun.
  • the swellable medium is arranged as a coating in the perforation gun.
  • a coating does not require an additional part in the perforation gun and is therefore easily integrated.
  • the coating is disposed on the interior of the gun barrel.
  • the coating may be applied to an additional thin-walled tube which is coaxial between the outer gun tube and the inner tube. Both tubes are excellent for one
  • the swellable medium is in another embodiment as a solid material, for example coming from the roll, on the gun barrel or an additional thin-walled tube, which is coaxial between the Cannon tube and the inner tube is applied by wrapping. Wrapping is a simple craft activity that is also cost effective.
  • the swellable medium can also be applied as a solid material, for example as a blank, to the gun barrel and / or an additional thin-walled tube, which is located coaxially between the gun barrel and the inner tube, exclusively in the area of the bullet holes. Round blanks are easy to produce and easy to apply.
  • the swellable medium itself is a tube or tube which is coaxial between the outer gun tube and the inner tube.

  • the swellable medium consists in a preferred embodiment of an elastomer compound, which by contact, for example, with
  • Explosion gas from perforators is activated and swells, causing the bullet holes to become clogged.
  • the swellable medium can also be activated by an approximation of the internal pressure of the gun to the pressure prevailing in the bore, which is generally much higher. This is done by the intended shooting through the cannon outer wall by means of the perforators brought into the cannon for ignition.
  • the swellable medium may be disposed as a coating in the perforating gun, be applied as a solid material by wrapping, or even be a tube or hose coaxial between the outer gun barrel and the inner tube.
  • the invention is characterized in that no “debris” (fragments of the perforators) fall into the bore, no external intervention is required to close the bullet holes.

Abstract

L'invention concerne un canon de perforation comportant un tube de canon extérieur à l'intérieur duquel est logé un tube intérieur de façon coaxiale, le tube intérieur portant des perforateurs pouvant être amorcés au moyen d'un cordeau détonant s'étendant à travers le tube de canon, les perforateurs perforant par ailleurs le tube de canon après amorçage afin de former des trous de tir. Des éléments sont prévus pour la fermeture automatique des trous de tir après le tir, ces éléments se présentant sous la forme d'un fluide gonflant. L'invention vise à obtenir un fluide gonflant nécessitant un espace réduit dans le canon de perforation et pouvant être intégré aisément dans le canon de perforation. A cet effet, le fluide gonflant est disposé sous forme plane à l'intérieur du canon de perforation.
