Claims (7)

  1. Verfahren zum Verringern der Wassermenge in einem aus einer Erdölbohrung zu fördernden Strom aus Öl und Wasser, wobei der Strom aufgelöstes Gas enthält, mit den Schritten:
    (a) Bereitstellen einer in das Bohrloch passenden Zyklonabscheidevorrichtung zum Aufspalten des Stroms aus Öl und Wasser in einen Strom höherer Dichte und einen Strom geringerer Dichte, wobei die Abscheidevorrichtung einen Einlaß, einen ersten Auslaß für den Strom geringerer Dichte und einen zweiten Auslaß für den Strom höherer Dichte hat;
    (b) Bereitstellen einer ersten Pumpe zum Pumpen von Flüssigkeiten in den Einlaß der Abscheidevorrichtung;
    (c) Verbinden des ersten Auslasses der Abscheidevorrichtung mit einer Leitung für eine Flüssigkeit geringerer Dichte, um den Strom geringerer Dichte zu erzeugen;
    (d) Verbinden des zweiten Auslasses der Abscheidevorrichtung mit einer Leitung für eine Flüssigkeit höherer Dichte, um den Strom höherer Dichte zu einer Untertageformation zu leiten;
    (e) Plazieren der Abscheidevorrichtung, der ersten Pumpe und der Leitung für die Flüssigkeit geringerer Dichte und der Leitung für die Flüssigkeit höherer Dichte in das Bohrloch; und
    (f) Einschalten der Pumpe, um die Flüssigkeiten durch die Abscheidevorrichtung und in die Leitungen für die Flüssigkeiten geringerer Dichte und höherer Dichte zu bewegen, ohne das Auftreten eines Gasausbruches zu gestatten.
  2. Verfahren nach Anspruch 1, bei dem die erste Pumpe so ausgewählt ist, daß sie genügend Druck in dem durch die Pumpe gehenden Strom aus Öl und Wasser erzeugt, um den größten Teil des gelösten Gases in Lösung zu halten, während der Strom durch die Pumpe und das Gehäuse geht.
  3. Verfahren nach Anspruch 1, zusätzlich mit dem Schritt, daß eine Gegendrucksteuerung in der Leitung für die Flüssigkeit höherer Dichte bereitgestellt wird.
  4. Verfahren nach Anspruch 3, bei dem die Gegegendrucksteuerung ein Ventil ist.
  5. Verfahren nach Anspruch 3, bei dem die Gegendrucksteuerung eine Öffnung ist.
  6. Verfahren nach Anspruch 1, zusätzlich mit dem Schritt, daß eine Gegenstromsteuerung in der Leitung für die Flüssigkeit höherer Dichte bereitgestellt wird.
  7. Verfahren nach Anspruch 1, zusätzlich mit dem Schritt, daß eine zweite Pumpe zwischen dein ersten Auslaß der Abscheidevorrichtung und der Leitung für die Flüssigkeit geringerer Dichte bereitgestellt wird, um den Strom geringerer Dichte bei der Bewegung zwecks Erzeugung des Stromes zu unterstützen, und daß die erste Pumpe so ausgewählt und betrieben wird, daß der größte Teil des gelösten Gases in Lösung gehalten wird, um somit das Auftreten eines Gasausbruches nicht zu gestatten, während der Strom durch die erste Pumpe, die Abscheidevorrichtung und in die zweite Pumpe geht.
