Abstract

La présente invention a trait à un procédé permettant de transmettre un fluide dans un puits de pétrole, lequel procédé fournit un cadre qui supporte une cuve, la cuve étant dotée de parties d'extrémité intérieure, supérieure et inférieure, d'une paroi latérale de forme conique et d'un orifice de sortie permettant d'évacuer le fluide à partir de la cuve. Un matériau polymère visqueux est ajouté à l'intérieur de la cuve. Un tuyau d'évacuation qui est doté d'une section verticale est placé sous la cuve, le tuyau d'évacuation étant en communication avec l'orifice de sortie. Une pompe volumétrique est contenue à l'intérieur du tuyau d'évacuation. La pompe transmet le fluide à partir de l'orifice de sortie jusque dans le tuyau d'évacuation en aval de la section de tuyau verticale ou de la pompe. Le fluide est transmis de façon sélective soit à l'intérieur de la cuve (afin d'être recyclé) soit dans le puits. De l'air est ajouté à la ligne d'écoulement d'évacuation en aval de la pompe. Selon un mode de réalisation, la cuve contient une vessie ou un sac souple qui contient le matériau qui doit être pompé. L'air met sous pression l'intérieur de manière à réduire la vessie ou le sac, ce qui permet de la sorte de faire passer le contenu du sac (à savoir le matériau qui doit être pompé) par un orifice de sortie d'évacuation prévu.
