Definitions

  • the pump cylinder section 8, the interlock section 10 and the drive cylinder section 12 all are provided with a centrally provided oil outlet channel 18, which is best shown in figures 6 and 7. Oil, which is sucked in through the mouth piece 4 by means of the piston pump 2, is guided into the oil outlet channel 18 by means of prior art control valves arranged in the pump valve section 6. The oil outlet channel 18 also continues through the control valve section 14 and the hydraulic drive unit 16 and exits in the well's production string 20. Thus, recovered oil may be pumped onwards to the surface.

Claims (5)

  1. Pompe à pistons (2) pour pomper du pétrole depuis une structure inférieure à la surface via un puits de pétrole, ladite pompe (2) étant connectée à des moyens de commande et d'entraînement pour commander et pour entraîner la pompe (2), respectivement, lorsqu'elle est placée dans le puits,
    caractérisée en ce que la pompe (2) comporte quatre ensembles à pistons (a, b, c, d) qui, au moyen d'un interverrouillage fixe (36) entre deux ensembles à pistons opposés (b, d), et au moyen d'un interverrouillage à roue dentée (38, 38') entre lesdits deux ensembles à pistons (b, d) et les deux autres ensembles à pistons opposés (a, c), sont conçus comme deux paires d'ensembles à pistons convergents (b, d et a, c).
  2. Pompe à piston (2) selon la revendication 1,
    caractérisée en ce que la pompe à pistons inclut, en séquence :
    - un tronçon formant cylindre de pompe (8) ;

    - un tronçon formant cylindre d'entraînement (12);
    tous ces tronçons étant dotés d'un canal de sortie de pétrole (18) ménagé au centre ;
    - dans laquelle le tronçon formant cylindre de pompe (8), le tronçon d'interverrouillage (10) et le tronçon formant cylindre d'entraînement (12) sont pourvus à l'intérieur de quatre ensembles à cylindres axiaux (A, B, C, D) distribués à la périphérie autour du canal de sortie de pétrole (18), chaque ensemble formant cylindre (A, B, C, D) comprenant :
    - un cylindre de pompe (22a, 22b, 22c, 22b) dans le tronçon formant cylindre de pompe (8) ;
    - une région en mouvement (24a, 24b, 24c, 24d), ouverte vers l'intérieur, dans le tronçon d'interverrouillage (10) ; et
    - un cylindre d'entraînement (26a, 26b, 26c, 26d) dans le tronçon formant cylindre d'entraînement (12) ;
    - dans laquelle chaque ensemble formant cylindre (A, B, C, D) est pourvu à l'intérieur d'un ensemble à piston axialement mobile (a, b, c, d), chaque ensemble à piston comprenant :
    - un piston de pompe (28a, 28b, 28c, 28 d) dans le cylindre de pompe (8) ;
    - une tige de piston (30a, 30b, 30c et 30d) dans la région en mouvement ouverte vers l'intérieur (24a, 24b, 24c, 24d) ; et
    - un piston d'entraînement (32a, 32b, 32c et 32d) dans le cylindre d'entraînement (26a, 26b, 26c, 26d) ;
    - dans laquelle deux tiges de piston (30b, 30d) diamétralement opposées sont mécaniquement connectées au moyen d'une tringlerie (36) prévue entre elles ;
    - dans laquelle chacune desdites tiges de piston (30b, 30d) mécaniquement connectées est connectée de façon mobile à l'une des deux autres tiges de piston (30a, 30c) via une roue dentée (38, 38') prévue entre elles, lesdites deux roues dentées (38, 38') étant supportée dans le tronçon d'interverrouillage (10) ; et
    - dans laquelle chaque tige de piston (30a, 30b, 30c et 30d) est dotée d'une portion en crémaillère (40) tournée vers ladite roue dentée (38, 38') et ayant une longueur correspondant au moins à la longueur de course desdits pistons.
  3. Pompe à piston (2) selon la revendication 2, caractérisée en ce que lesdits quatre ensembles à cylindres axiaux (A, B, C, B) distribués en périphérie autour du canal de sortie de pétrole (18) sont distribués à une distance angulaire égale les uns par rapport aux autres.
  4. Pompe à pistons (2) selon la revendication 2 ou 3, caractérisée en ce que ladite région en mouvement ouverte vers l'intérieur dans le tronçon d'interverrouillage (10) est constituée de gorges (24a, 24b, 24c, 24d) partiellement en forme de cylindre.
  5. Pompe à pistons (2) selon la revendication 2, 3 ou 4, caractérisée en ce que ladite tringlerie mécanique dans le tronçon d'interverrouillage (10) est constituée d'une plaque de liaison (36).
