  11. Bohranlage nach Anspruch 10, wobei die Kabelschaufelvorrichtung umfasst:
    eine oder mehrere schwenkbar montierte Schaufeln, wobei jede Schaufel einen Arm und ein Schaufelende aufweist, zum Schwenken in einer Ebene im Wesentlichen senkrecht zur Schusslinie, d.h. die Mittelachse des Rohrs, wobei ein oder mehrere Schaufelenden eine Vorderseite zum Schaufeln des Kabels und/oder der Steuerleitung und eine Rückseite aufweisen, und wobei die eine oder mehreren Schaufeln jeweils federnd in einer Schaufelposition gehalten werden, so dass durch Bewegen des Kabels und/oder der Steuerleitung gegen die Rückseite des Schaufelendes, die Schaufel von dem Rohr weg schwenkt, um den Durchgang der Kabel- und/oder Steuerleitungen zwischen der Schaufel und dem Rohr in Richtung der Vorderseite der Kabelschaufel zu ermöglichen und um anschließend die Kabel- und/oder Steuerleitungen in eine entgegengesetzte Richtung zu bewegen, um so der Schaufel zu ermöglichen mit Kabeln und/oder Steuerleitungen in Eingriff zu kommen, und um anschließend die Kabel und/oder Steuerleitungen in eine Richtung weg vom Rohr zu bewegen, z.B. in eine Halteposition, und
    wobei die Kabelschaufelvorrichtung vorzugsweise drehbar gestützt ist, so dass die Kabelschaufelvorrichtung um eine Achse schwenken kann, die mit der Schusslinie zusammenfällt, und so, dass durch das Schwenken der Kabelschaufelvorrichtung mit der einen oder mehreren Schaufeln in der Schaufelposition das eine oder die mehreren entsprechenden Schaufelenden entlang des Umfangs des Rohrs bewegt wird/werden.
  12. Bohranlage nach einem oder mehreren der vorstehenden Ansprüche, wobei die Bohranlage ferner eine zweite Kabelschaufelvorrichtung nach Anspruch 10 oder Anspruch 11 umfasst, und wobei eine Kabelschaufelvorrichtung neben und über der Haltevorrichtung , und eine Kabelschaufelvorrichtung neben und unter der Haltevorrichtung angeordnet ist, für das unisono Schaufeln der Kabel und/oder Steuerleitungen und Bewegen der Kabel und/oder Steuerleitungen in eine Halteposition in einem Abstand von der Außenseite des Rohrs.
  13. Verfahren zum Entfernen eines Rohrs (2016) aus einem Bohrloch, vorzugsweise aus einem Kohlenwasserstoffbohrloch, vorzugsweise unter Verwendung einer Bohranlage (2001) und/oder einer Kabelklemmenentfernungsvorrichtung (2120) und/oder einer Röhrenverbindungsaufbau- und -unterbrechungsvorrichtung (2130) und/oder einer Kabelschaufelvorrichtung (3000; 4000) gemäß einem oder mehreren der vorhergehenden Ansprüche, wobei das Verfahren die Schritte umfasst:
    - in Eingriff Kommen mit einem oberen Ende des Rohrs (2016) ;
    - Anheben des Rohrs (2016) aus dem Bohrloch heraus in eine Kabel- und/oder Steuerleitungenschaufelposition;
    - Schaufeln der Kabel und/oder Steuerleitungen (2117) von der Außenseite des Rohrs (2016), um das Rohr mit einer befreiten äußeren Stützzone für den Eingriff durch eine Haltevorrichtung (2032) zu versehen, wobei die Stützzone vorzugsweise unter einer an dem Rohr (2016) montierten Kabelklemme (2136) angeordnet ist;
    - Bringen, vorzugsweise ferner Anheben, des Rohrs (2016) in eine Stützposition, in der die Stützzone zum Eingriff durch die Haltevorrichtung (2032) positioniert ist; z.B. wobei die Haltevorrichtung in oder auf einem Arbeitsdeck (2031) einer Bohranlage (2001) angeordnet ist;
    - in Eingriff Kommen mit dem Rohr (2016) an der Stützzone mit der Haltevorrichtung (2032) und Aufhängen des Rohrs (2016) mit der Haltevorrichtung (2032), so dass ein über der Haltevorrichtung (2032) angeordneter Röhrenständer von dem aufgehängten Rohr getrennt werden kann;
    - Entfernen der Kabelklemme (2136) von dem Rohr (2016), vorzugsweise durch Eintreiben eines Keils (2122) zwischen einen Ring der Kabelklemme (2136) und das Rohr (2016);
    - Trennen des Röhrenständers von dem aufgehängten Rohr (2016) durch Schneiden oder Herausbrechen;
    - Anheben des Rohrs (2016) aus dem Bohrloch heraus in eine Kabel- und/oder Steuerleitungsschaufelposition, während das Kabel und/oder die Steuerleitungen (2117) von dem Rohr weggeführt werden, vorzugsweise durch Aufwickeln des Kabels und/oder der Steuerleitungen auf eine Lagerungsrolle (2042);
    - Wiederholen der obigen Schritte.
  14. Verfahren nach Anspruch 13, das ferner die Schritte umfasst:
    Schneiden des Röhrenständers in Rohrabschnitte außerhalb der Linie, vorzugsweise nach vorübergehender Lagerung des Röhrenständers in einem Griffbrett;
    Bewegen des Röhrenständers in eine Schneideposition relativ zu einer Schneidevorrichtung; und
    Stützen des Röhrenständers, vorzugsweise mit einer im Wesentlichen vertikalen Ausrichtung und vorzugsweise mit einem unteren Ende des Röhrenständers in einer Rohrabschnittslagerungsvorrichtung, in der Schneideposition und Schneiden des Röhrenständers in einen oder mehrere Abschnitte.
  15. Verfahren nach Anspruch 13 oder Anspruch 14, ferner umfassend das Positionieren der Kabel und/oder Steuerleitungen relativ zu der Kabelklemmenentfernungsvorrichtung und/oder der Kabelschaufelvorrichtung und/oder dem Kabelführungssystem durch Schwenken des Rohrs, d.h. Schwenken des Rohrs um eine Achse, die mit der Schusslinie zusammenfällt, z.B. unter Verwendung der Haltevorrichtung , z.B. in Form eines Drehtisches, oder des auslösenden Betriebsaufzugs zum Schwenken des Rohrs, wobei der auslösende Betriebsaufzug z.B. einen oberen Antrieb zum Drehen des Rohrs umfasst.
