Abstract

L'invention concerne un procédé d'extraction de liquide non gazeux en nappe, procédé qui peut être utilisé pour extraire des puits profonds de l'eau en nappe et d'autres liquides non gazeux. Le procédé consiste à faire le remonter le liquide par des pompes. Pour cela, on crée un courant continu de liquide en alternant des cycles d'admission et d'évacuation des chambres de travail de pompes de substitution à deux chambres interchangeables pour le forage de puits qui sont raccordées par des conduites destinées au liquide extrait en vue de refouler le gaz d'échappement, et par un câble d'alimentation électrique. A cette fin, on augmente la pression dans l'espace annulaire du tubage de puits hermétiquement fermé, dans lequel le niveau statique du liquide est réduit à un niveau inférieur à celui auquel se trouve l'étage inférieur de la pompe de substitution pour le forage de puits du fait de la différence de l'augmentation de pression dans l'espace annulaire du tubage de puits, de la pression dans la conduite de renvoi du gaz d'échappement qui débouche dans l'atmosphère, et dans l'une des chambres de travail de la pompe à l'étage inférieur de l'installation. Puis s'effectue l'admission du liquide, mais qui est ensuite refoulé, depuis une autre chambre de toutes les pompes le long de la conduite destinée au liquide extrait, vers des pompes dans les étages supérieurs sous l'effet du passage du gaz comprimé provenant de l'espace annulaire du tubage de puits. L'admission du liquide par les chambres de travail des pompes situées dans le haut est conditionnée par le refoulement du liquide des chambres de travail situées en contrebas des pompes.
