Claims (9)

  1. Dispositif pour la transmission d'informations à l'intérieur d'une colonne de tiges (1) d'un dispositif de forage (2) à l'aide d'impulsions de pression dans un liquide qui s'écoule, en particulier de la boue de forage (F), comprenant un dispositif de génération d'informations (3), un dispositif de transmission (4) raccordé au dispositif de génération d'informations (3) pour générer des impulsions de pression dans le liquide, et un dispositif de réception (5) pour la réception et l'évaluation des informations transmises via les impulsions de pression, dans lequel le dispositif de transmission (4) présente un corps élastique à résistance hydraulique (6) dans le courant de liquide et un dispositif de réglage (7) pour la modification de la section de passage (Q) du corps à résistance hydraulique (6) de manière synchrone aux impulsions de pression à générer, caractérisé en ce que le corps à résistance hydraulique est constitué de caoutchouc ou d'une substance synthétique élastique, par exemple d'un élastomère possédant une dureté Shore prédéterminée.
  2. Dispositif selon la revendication 1, caractérisé en ce que le corps à résistance hydraulique (6) est réalisé sous la forme d'un corps élastique creux, par exemple une sphère creuse, un tore ou un cylindre creux comportant des rétrécissements biconcaves.
  3. Dispositif selon la revendication 1 ou 2, caractérisé en ce que le corps à résistance hydraulique (6) est composé de plusieurs corps creux.
  4. Dispositif selon la revendication 3, caractérisé en ce que les corps creux peuvent être commandés de manière individuelle, de manière conjointe ou en alternance par le dispositif de réglage (7).
  5. Dispositif selon l'une quelconque des revendications 1 à 4, caractérisé en ce que le dispositif de réglage (7) peut être entraíné par voie mécanique, par voie pneumatique ou par voie hydraulique.
  6. Dispositif selon l'une quelconque des revendications 1 à 5, caractérisé en ce que le corps à résistance hydraulique (6) est réalisé sous la forme d'une membrane (8) fixée dans la colonne de tiges (1), dont le côté supérieur est disposé, dans la direction d'écoulement du courant de liquide, à la périphérie (9) du courant de liquide, tandis que son côté inférieur peut être sollicité par le dispositif de réglage (7).
  7. Dispositif selon la revendication 6, caractérisé en ce que le dispositif de réglage (7) est réalisé sous la forme d'un conduit de dérivation (11) pour le courant de liquide, raccordé au côté inférieur de la membrane (8) et apte à être fermé par une soupape de commande (10).
  8. Dispositif selon la revendication 7, caractérisé en ce qu'on prévoit deux membranes opposées (8a, 8b) à la périphérie respective (9) du courant de liquide comprenant des conduits de dérivation respectifs (11a, 11b).
  9. Dispositif selon la revendication 8, caractérisé en ce que les deux membranes (8a, 8b) comprenant les deux conduits de dérivation (11a, 11b) peuvent être sollicités par une soupape de commande commune (10).
