Abstract
Description
Die Erfindung betrifft eine Vorrichtung und Verfahren, mit dem man Öl-Bohrungen sowohl unter Wasser, als auch auf dem Land zuverlässig schließen kann.The invention relates to a device and method that can reliably close oil wells both under water, as well as on land.
Mit dem Bevölkerungszuwachs steigt der Bedarf nach Energie und Rohstoffen. Insbesondere die Öl-Quellen werden immer wichtiger. Auf dem Meeresboden sind sehr grosse Ölmengen vorhanden, die durch Bohrplattformen befördert werden.With population growth, the demand for energy and raw materials is increasing. In particular, the oil sources are becoming increasingly important. There are very large quantities of oil on the seabed, which are transported by drilling platforms.
Durch den Öl-Bohr-Plattformen oder wie man diese anders auch Bohrinsel nennt, werden Bohrungen in den Tiefen durchgeführt, wobei das Öl aus den Meeresboden an die Oberfläche befördert wird. Das Öl wird dann entweder durch lange Pipelines oder durch Tankerschiffe abtransportiert. Es kann allerdings, wie das jüngste Beispiel zeigt, zu Unfällen und zu Austreten des Öls kommen. In dem Fall vor dem Golf von Mexico, ist eine Plattform in Brand geraten und danach gesunken. Das Bohrloch wurde nicht wie vorgesehen verschlossen, sondern blieb offen und dutzende millionen Liter von Öl strömten täglich ungehindert ins Meereswasser.Through the oil drilling platforms, or otherwise called drilling rigs, drilling is carried out in the depths, transporting the oil from the seabed to the surface. The oil is then transported either by long pipelines or by tanker ships. However, as the most recent example shows, it can lead to accidents and oil spills. In the case off the Gulf of Mexico, a platform has caught fire and then sunk. The well was not closed as intended, but remained open and tens of millions of liters of oil flowed daily unhindered into the sea water.
Um das Bohrloch zu schließen, gibt es zahlreiche Methoden und Verfahren. In der Regel werden Sicherheitsventile eingebaut, die in der Lage sind, sich selbst zu schließen, wenn zu einem Unfall kommen sollte. Falls dennoch das Ventil offen bleibt, wird versucht eine Art Glocke drüber zu stülpen, die das Austreten des Öls verhindern soll. In dem Golf von Mexico wurden zwei Versuche unternommen, die sprudelnde Quelle mit Glocken zu schließen. Allerdings ohne Erfolg. Man hat auch versucht mit Chemikalien das Öl unschädlich zu machen, aber bei solchen gewaltigen Mengen an Öl, hat das leider kaum einen sichtbaren Effekt. Auch ein sog. Top-Kill Verfahren, wobei das Bohrloch mit Schlamm und Zusätze (Golfbälle, Reifenteile und weitere Gegenstände) befüllt wird, zeigte leider keinen Effekt.To close the well, there are many methods and procedures. As a rule, safety valves are installed which are able to close themselves if an accident should occur. If, nevertheless, the valve remains open, an attempt is made to put over it a bell over which is to prevent the escape of the oil. In the Gulf of Mexico, two attempts have been made to close the bubbling spring with bells. But without success. It has also been tried with chemicals to make the oil harmless, but with such huge amounts of oil, this unfortunately has hardly any visible effect. Also, a so-called top-kill procedure, whereby the hole is filled with mud and additives (golf balls, tire parts and other items), unfortunately showed no effect.
Es werden zahlreiche Schutzmechanismen beschrieben, allerdings letztendlich ist der Faktor Mensch auch mit zu berücksichtigen.Numerous protective mechanisms are described, but ultimately the human factor must also be taken into account.

All diese Verfahren eignen sich allerdings nicht für Ölbohrungen, die sich tief unter dem Meereswasser befinden.However, all of these methods are not suitable for oil wells deep under the sea.
Der in den Patentansprüchen 1 und 2, sowie den Unteransprüchen 3 bis 26 angegebenen Erfindung liegt das Problem zugrunde, eine zuverlässiges Verfahren und eine passende Vorrichtung zu schaffen, die in der Lage ist, jede beliebige Ölquelle, bzw. Öl-Bohrung zuverlässig zu schließen.The invention disclosed in

Vorteile der Erfindung sind:
- – Sehr schnelle Einsatzbereitschaft,
- – zuverlässiges und schnelles Schließen einer Bohrung nahezu unabhängig von dem Durchmesser der Bohrung
- – sehr günstiges Verfahren und Vorrichtung
- - very fast operational readiness,
- - Reliable and fast closing of a bore almost independent of the diameter of the bore
- - Very cheap process and device

Die Erfindung ist eine zuverlässige Lösung, die eine außer Kontrolle geratene Ölbohrung schließen kann.The invention is a reliable solution that can close an out of control oil well.
Die Vorrichtung (
Eine Variante aus der
Dieses Verfahren hat den Vorteil, weil man damit relativ schonend, gefahrlos ein defektes Ventil in die Bohrung, geschlossen werden kann. Sie ist flexibel und kann das Ventil oder Endrohr auch beim Versagen nicht beschädigen. Sie umschließt sanft, wobei die Kraft sehr homogen doch sehr fest auf der ganzen Oberfläche des Endrohrs oder Ventils der Bohrung in dem Schließbereich übertragen wird, und erlaubt zudem dass ein eingebautes Rohr am anderen Ende der Überstülpung beweglich bleibt. Das Ventil oder Endrohr wird großflächig umschlossen. Anders als bei Überstülpungen aus festem Material, besteht hier keine Gefahr, dass die Kraft punktuell oder in kleinen Bereichen übertragen wird.This method has the advantage that you can thus relatively gently, safely a defective valve in the hole, closed. It is flexible and can not damage the valve or tailpipe even in the event of failure. It wraps gently, transferring the force very homogeneously but very firmly all over the surface of the tailpipe or valve of the bore in the closing area, and also allows a built-in tube to remain movable at the other end of the protuberance. The valve or tailpipe is enclosed over a large area. Unlike with solid material overrides, there is no danger that the force will be transmitted selectively or in small areas.
Allerdings muss das Ventil oder ein Stück Rohr noch aussen übriggeblieben sein. Wenn die Bohrung überhaupt nicht richtig ausgebaut ist und kein Rohr außerhalb des Bodens herausragt, ist das Verfahren ungeeignet.However, the valve or a piece of pipe must still be left outside. If the hole is not removed at all and no pipe protrudes out of the ground, the method is unsuitable.
