Claims (15)

  1. Bohrlochanordnung (10) zum Steuern der Wärmeübertragung zwischen einem Rohrelement (22), welches in einem Bohrloch (14) angeordnet ist, und einem Bohrlochsystem (12), wobei die Anordnung (10) umfasst:
    ein Rohrelement (22), welches zum Transportieren eines erzeugten Fluids aus einem unterirdischen Reservoir (20) zu einer Oberflächenstruktur ausgebildet ist, wobei das erzeugte Fluid einen Druckgradienten entlang der Länge des Rohrelements (22) umfasst oder aufweist;
    ein unteres Element (28), welches zwischen dem Rohrelement (22) und einer Wand (18) eines Bohrlochsystems (12) bereitgestellt ist;
    einen Raum (26), welcher sich in einer Bohrloch-Aufwärtsrichtung von dem unteren Element (28) und zwischen dem Rohrelement (22) und einer Wand (18) des Bohrlochsystems (12) erstreckt;
    ein Isolierfluid (36), welches mindestens teilweise den Raum (26) füllt; und
    eine Steueranordnung (38) zum Einstellen eines Drucks des Isolierfluids (36) in dem Raum (26), sodass ein Druckgradient des Isolierfluids (36) entlang der Länge des Rohrelements (22) gesteuert wird, um dem Druckgradienten des erzeugten Fluids zu entsprechen oder diesen zu folgen.
  2. Bohrlochanordnung nach Anspruch 1, wobei die Steueranordnung (38) betreibbar ist, um die Steuerung der Wärmeübertragung zwischen dem Rohrelement (22) und dem Bohrlochsystem (12) und/oder einer Bohrlochformation (14) zu ermöglichen, welche an dem Bohrlochsystem angrenzt.
  3. Bohrlochanordnung nach Anspruch 1 oder 2, wobei die Steueranordnung (38) betreibbar ist, um das Isolierfluid (36) in dem Raum (26) intermittierend oder kontinuierlich umzuwälzen, optional
    wobei das Isolierfluid (36) in dem Raum (36) vorwärts und/oder rückwärts umgewälzt wird.
  4. Bohrlochanordnung nach einem der vorhergehenden Ansprüche, wobei das Isolierfluid (36) ein Fluid mit einer niedrigen Wärmeleitfähigkeit umfasst, optional
    wobei das Isolierfluid (36) mindestens eines von Stickstoff, Krypton, Argon und Xenon umfasst.
  5. Bohrlochanordnung nach einem der vorhergehenden Ansprüche, wobei das Isolierfluid (36) dazu beiträgt, die Wärmeübertragung von dem erzeugten Fluid zu dem Bohrlochsystem (12) und/oder einer Bohrlochformation (14) zu minimisieren.
  6. Bohrlochanordnung nach einem der vorhergehenden Ansprüche, wobei der Druckgradient des erzeugten Fluids angepasst oder verfolgt wird, indem ein Isolierfluid (36) ausgewählt wird, welches im Wesentlichen denselben oder einen ähnlichen hydrostatischen Druck aufweist, wie der des erzeugten Fluids.
  7. Bohrlochanordnung nach einem der vorhergehenden Ansprüche, wobei das Rohrelement (22) konfiguriert ist, um die Übertragung von Wärmeenergie/Wärme von dem erzeugten Fluid, welches in demselben enthalten ist oder darin strömt, an das Bohrlochsystem (12) und/oder an die Bohrlochformation (14) zu reduzieren, optional
    wobei das Rohrelement (22) eine Isolierkammer (40) zum Minimisieren der Wärme-/Wärmeenergie-Übertragung von dem erzeugten Fluid an das Bohrlochsystem (12) umfasst.
  8. Bohrlochanordnung nach einem der vorhergehenden Ansprüche, wobei das untere Element (28) eine Abdichtung des Rohrelements (22) und des Bohrlochsystems (12) bereitstellt, optional
    wobei das untere Element (28) einen Produktionspacker umfasst.
  9. Bohrlochanordnung nach einem der vorhergehenden Ansprüche, umfassend ein oberes Element (32), wobei der Raum (26) ein ringförmiger Raum ist, welcher sich zwischen dem unteren (28) und dem oberen (32) Element erstreckt, wobei das obere Element (32) eine weitere fluidische Abdichtung des Isolierfluids (36) in einer Bohrloch-Aufwärtsrichtung bereitstellt, optional
    wobei das obere Element (32) einen Rohraufhänger umfasst.
  10. Bohrlochanordnung nach einem der vorhergehenden Ansprüche, umfassend einen Behälter oder Kammer (46), welche eine Quelle (48) des Isolierfluids (36) umfasst.
  11. Bohrlochanordnung nach einem der vorhergehenden Ansprüche, umfassend mindestens eine Pumpe und/oder eine Kompressoranordnung (50), welche konfiguriert ist, um den Druck des Isolierfluids (36) in dem Raum (26) zu steuern.
  12. Bohrlochanordnung nach einem der vorhergehenden Ansprüche, umfassend mindestens ein erstes Leitungselement (52a) zum Leiten und/oder Übertragen des Isolierfluids (36) zu/von dem Raum (26), wobei das erste Leitungselement (52a) sich entlang der Länge des Rohrelements (22) bis oberhalb des unteren Elements (28) erstreckt.
  13. Bohrlochanordnung nach einem der vorhergehenden Ansprüche, umfassend mindestens eine Sensoranordnung (52), welche in dem Raum (26) und/oder auf dem Rohrelement (22) angeordnet oder bereitgestellt ist.
  14. Verfahren zum Steuern der Wärmeübertragung zwischen einem Rohrelement (22), welches in einem Bohrlochformation (14) angeordnet ist, und einem Bohrlochsystem (12), wobei das Verfahren umfasst:
    Anordnen eines Rohrelements (22) innerhalb des Bohrlochs (14);
    Bereitstellen eines unteren Elements (28) zwischen dem Rohrelement (22) und einer Wand (18) des Bohrlochsystems (12);
    Bereitstellen einer Strömung eines erzeugten Fluids durch das Rohrelement (22) aus einem unterirdischen Reservoir (20) zu einer Oberflächenstruktur, wobei das erzeugte Fluid einen Druckgradienten entlang der Länge des Rohrelements umfasst oder aufweist;
    mindestens teilweises Füllen eines Raums (26) mit einem Isolierfluid (36), wobei der Raum (26) sich in einer Bohrloch-Aufwärtsrichtung von dem unteren Element (28) und zwischen dem Rohrelement (22) und einer Wand (16b) eines Bohrlochsystems (12) erstreckt, und
    Einstellen eines Drucks des Isolierfluids (36) in dem Raum (26), sodass ein Druckgradient des Isolierfluids entlang der Länge des Rohrelements (22) gesteuert wird, um dem Druckgradienten des erzeugten Fluids zu entsprechen oder diesen zu verfolgen.
  15. Verfahren nach Anspruch 14, umfassend das Einstellen, Verändern und/oder Modifizieren des Druckgradienten des Isolierfluids (36), um dem Druckgradienten des erzeugten Fluids zu entsprechen oder diesen zu verfolgen.
