Definitions

  • Directional drilling is the process that makes it possible to influence the direction of a deep well.
  • the layer of rock 20 in which the shale gas is stored is often several thousand meters below the surface of the earth (depth T).
  • the relevant for gas production layer thickness D of the rock layer 20 is the opposite, for example, only 20 to 30 m.
  • it is therefore necessary to let the bore hole 10 approximately horizontally through the rock stratum 20 duri ⁇ fen.
  • the gas adsorbed by the claystone may be delayed by the decaying pressure after the production of the wellbore 10 is absorbed.

Abstract

L'invention concerne un procédé d'extraction de gaz de schiste par l'intermédiaire d'un trou de forage (10) creusé à travers un forage directionnel, le gaz de schiste étant accumulé dans une couche rocheuse (20) fermée. Le procédé consiste à injecter un fluide de fracturation (F) dans le trou de forage (10). Lorsque le fluide de fracturation (F) atteint une pression prédéfinie à l'intérieur du trou de forage (10), le trou de forage est fermé de manière résistante à la pression. Le fluide de fracturation (F) est chauffé pour augmenter la pression au-delà de la plus petite tension présente dans la couche rocheuse.
