Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Verbinden von zumindest einer elektrischen Daten- und/oder Versorgungsleitung mit elektrischen Anschlüssen eines verdrahteten Bohrrohrs, wenn sich das Bohrrohr nicht im aktiven Bohrbetrieb befindet.The invention relates to a device for connecting at least one electrical data and / or supply line to electrical connections of a wired drill pipe when the drill pipe is not in active drilling operation.
Derzeit werden an vielen Bohranlagen einfache Stahlrohre miteinander verschraubt. Auf diese Weise entsteht ein meist mehrere Kilometer langes Bohrgestänge, an dessen Ende ein Bohrmeißel befestigt ist. Im Inneren der Rohre befindet sich eine Spülflüssigkeit (Mud), die vielerlei Funktionen während des Bohrvorgangs erfüllt. Eine dieser Funktionen kann die Übertragung von Daten mittels Druckpulsen sein. Da diese Kommunikation aber sehr langsam ist (die Übertragungsrate liegt typischerweise bei 10 Baud), wurden in der Bohrindustrie verstärkte Anstrengungen unternommen, um während des Bohrbetriebs Bohrlochinformation mit höheren Datenübertragungsraten gewinnen zu können. Aus dem Dokument
Mittlerweile ist die Erfassung von Daten aus dem Bohrloch während des Bohrvorgangs ein wesentliches Element bei modernen Erdöl-, Erdgas- oder Geothermiebohrungen geworden. Diese Art von Datenerfassung wird im Fachjargon als Measurement While Drilling (MWD) oder Logging While Drilling (LWD) bezeichnet. Die Datenerfassung ist aber auch für die Konstruktion des Bohrlochs und die anschließende Förderung von Erdöl, Gas oder Warmwasser wichtig. Nur durch die Erfassung der jeweiligen relevanten Messgrößen kann eine Bohrung sicher, effizient und ökonomisch betrieben werden. Je mehr Daten von Untertag zur Verfügung stehen, umso effizienter und sicherer kann der Bohrbetrieb gestaltet werden. Die Bohrindustrie fordert daher immer dringender eine Übertragung von Daten mit hohen Datenraten (z.B. 200 kBaud) aus mehreren Kilometern Tiefe. Diese Forderung resultiert in erhöhten Anforderungen an die Leistungsfähigkeit von Untertagmesseinheiten, die wiederum zu einem Anstieg des Stromverbrauchs der Untertagmesseinheiten führt. Um diesem erhöhten Stromverbrauch Rechnung zu tragen, sollen die Untertagmesseinheiten auch von der Oberfläche aus mit elektrischer Energie (z.B. mit 200 W) versorgt werden.Meanwhile, logging data from the well during the drilling process has become an essential element in modern oil, gas or geothermal wells. This type of data collection is referred to in the jargon as Measurement While Drilling (MWD) or Logging While Drilling (LWD). The data acquisition is also important for the construction of the borehole and the subsequent extraction of oil, gas or hot water. Only by recording the respective relevant parameters can a well be operated safely, efficiently and economically. The more data available from Untertag, the more efficient and safer the drilling operation can be. The drilling industry is therefore increasingly calling for a transfer of data high data rates (eg 200 kBaud) from several kilometers depth. This requirement results in increased demands on the performance of underground units, which in turn leads to an increase in the power consumption of underground units. In order to take account of this increased power consumption, the underground units should also be supplied with electrical energy (eg 200 W) from the surface.
Aus dem Dokument
Insbesondere für die Erhöhung der Sicherheit des Bohrlochs ist es jedoch auch erforderlich, Energieversorgung für Untertagmesseinheiten bereitzustellen und Daten auszulesen, wenn kein Bohrvorgang durchgeführt wird, sondern das Bohrgestänge ausgebaut (Trip-out) oder durch Zusammensetzen von Rohren eingebaut (Trip-in) wird. Gerade in dieser Phase ist es von höchster Wichtigkeit zu wissen, ob sich im Bohrloch sicherheitsrelevante Veränderungen ergeben, wie z.B. Druckveränderungen, Reibung, Gasblasenbildung, etc..In particular, for increasing the safety of the well, however, it is also necessary to provide power supply for underground units and read data when no drilling operation is performed, but the drill pipe is removed (trip-out) or built-in (trip-in) by pipes. At this stage in particular, it is of paramount importance to know whether there are safety-relevant changes in the borehole, such as Pressure changes, friction, gas bubble formation, etc ..

Das Dokument
Die Absicht Energie, Daten und/oder Steuersignale während des Trip-in bzw. Trip-out Betriebs des Bohrlochs in das Bohrgestänge einzuspeisen bzw. daraus auszuspeisen, stößt vor allem auf folgende Schwierigkeiten:
- Das Bohrgestänge ist nicht regulär am Schleifringensemble angeschraubt, das daher nicht zur elektrischen Versorgung und Kommunikation verwendet werden kann.
- Elektrische Energieversorgungseinheiten, Datenverarbeitungsgeräte und Steuerungen befinden sich aus Sicherheitsgründen außerhalb des Bohrturms in einem Schaltschrank und müssen über Energieversorgungs-, Status- und Steuerleitungen mit dem Bohrgestänge verbunden werden.
- Die Energieversorgungs-, Status- und Steuerleitungen müssen über eine elektromechanische Einheit mit dem Bohrgestänge in Verbindung gebracht werden, die unter den rauen Betriebsbedingungen und unter Einhaltung von Sicherheitsvorschriften wie jenen für die Explosionsschutzzone 1 höchst zuverlässig funktioniert und für das Bedienungspersonal dennoch einfach handhabbar ist, wobei halbautomatisches oder manuelles Verbinden und Trennen möglich sein soll.
- The drill string is not normally bolted to the slip ring ensemble, which therefore can not be used for electrical supply and communication.
- Electrical power units, data processing equipment and controllers are located outside the derrick in a cabinet for safety reasons and must be connected to the drill string via power, status and control lines.
- The power, status, and control lines must be connected to the drill pipe via an electromechanical unit, which operates highly reliably under harsh operating conditions and in compliance with safety regulations such as those for explosion protection zone 1, yet is easy to handle for the operator semi-automatic or manual connection and disconnection should be possible.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Lösung für die oben diskutierten Probleme bei der Einspeisung und Ausspeisung von elektrischer Energie, Daten und/oder Steuersignalen während des Trip-in bzw. Trip-out Betriebs des Bohrlochs in das Bohrgestänge bereitzustellen.It is an object of the present invention to provide a solution to the problems discussed above of feeding and offsetting electrical energy, data and / or control signals during trip-in or down-hole operation of the wellbore.
Diese Aufgabe wird durch eine Vorrichtung zum Verbinden von zumindest einer elektrischen Daten- und/oder Versorgungsleitung mit elektrischen Anschlüssen eines verdrahteten Bohrrohrs mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen, der Beschreibung und den Zeichnungen dargelegt.This object is achieved by a device for connecting at least one electrical data and / or supply line to electrical connections of a wired drill pipe having the features of claim 1.

Das Axialführungselement und das Axialverriegelungselement sind relativ zueinander zwischen einer Axialverriegelungsstellung und einer Freigabestellung axial verlagerbar, wobei in der Axialverriegelungsstellung das Axialverriegelungselement zum Ineinandergreifen mit dem Bohrrohr konfiguriert ist, und wobei in der Freigabestellung der Eingriff des Axialverriegelungselements in das Bohrrohr gelöst ist.By means of the connecting device according to the invention, at least one electrical data and / or supply line can be connected to electrical connections of a wired drill pipe when the drill pipe is not in active drilling operation. The connecting device according to the invention comprises: electrical connections, which are galvanically connected to the at least one electrical data and / or supply line and can be brought into contact with the electrical connections of the drill pipe; an axial guide element axially insertable and removable in a receiving end of the drill pipe; and at least one Axialverriegelungselement. The axial guide member and the axial locking member are axially displaceable relative to each other between an axial locking position and a release position, wherein in the Axialverriegelungsstellung the Axialverriegelungselement is configured to mesh with the drill pipe, and wherein in the release position of the engagement of the Axialverriegelungselements is dissolved in the drill pipe.
Die erfindungsgemäße Verbindungsvorrichtung eignet sich besonders gut zur Verbindung mit den in der oben erwähnten Patentanmeldung
Eine schnell und sicher herstellbare Verriegelung zwischen der erfindungsgemäßen Verbindungsvorrichtung und dem Bohrrohr lässt sich erzielen, wenn das Axialverriegelungselement radial beweglich ist, vorzugsweise elastisch radial beweglich ist.A quick and secure manufacturable locking between the connecting device according to the invention and the drill pipe can be achieved if the Axialverriegelungselement is radially movable, preferably elastically radially movable.
Wenn beim erfindungsgemäßen Verbindungsvorrichtung das Axialverriegelungselement in der Freigabestellung radial einziehbar ist, lässt sich die Verbindungsvorrichtung besonders einfach aus dem Bohrrohr herausführen. In einer bevorzugten Konstruktion der Erfindung weist das Axialführungselement zumindest eine Vertiefung, vorzugsweise zumindest eine Umfangsnut, auf, in die in der Freigabestellung das Axialverriegelungselement radial einziehbar ist. Eine besonders sichere Handhabung der erfindungsgemäßen Verbindungsvorrichtung lässt sich erzielen, wenn das Axialführungselement zwei axial versetzte Vertiefungen, vorzugsweise Umfangsnuten, aufweist, die zwei unterschiedliche Freigabestellungen definieren. Dabei wird eine erste Freigabestellung durch relative axiale Verlagerung des Axialführungselements zum Axialverriegelungselement in eine erste Richtung eingenommen, und eine zweite Freigabestellung durch relative axiale Verlagerung des Axialführungselements zum Axialverriegelungselement in die Gegenrichtung eingenommen. Hohe mechanische Stabilität der Verbindung zwischen der Verbindungsvorrichtung und dem verdrahteten Bohrrohr und Schutz gegen Lösen der Verbindung bei Auftreten von Zugkräften erreicht man, wenn in der Axialverriegelungsstellung ein Abschnitt des Axialführungselements ein Widerlager gegen radiales Einziehen des Axialverriegelungselements bildet.If, in the connection device according to the invention, the axial locking element can be radially retracted in the release position, the connecting device can be guided out of the drill pipe in a particularly simple manner. In a preferred construction of the invention, the axial guide element has at least one recess, preferably at least one circumferential groove, into which the axial locking element can be radially retracted in the release position. A particularly secure handling of the connecting device according to the invention can be achieved if the axial guide element has two axially offset recesses, preferably circumferential grooves, which define two different release positions. In this case, a first release position is assumed by relative axial displacement of the Axialführungselements to Axialverriegelungselement in a first direction, and a second release position occupied by relative axial displacement of the Axialführungselements to Axialverriegelungselement in the opposite direction. High mechanical stability of the connection between the connecting device and the wired drill pipe and protection against loosening of the connection when tensile forces occur, when in the axial locking position, a portion of the Axialführungselements forms an abutment against radial retraction of the Axialverriegelungselements.
Gute Handhabbarkeit der erfindungsgemäßen Verbindungsvorrichtung wird erzielt, wenn das Axialverriegelungselement Vorsprünge aufweist, die konfiguriert sind, um in der Axialverriegelungsstellung in Vertiefungen des Bohrrohrs einzugreifen, oder wenn das Axialverriegelungselement Vertiefungen aufweist, die konfiguriert sind, um in der Axialverriegelungsstellung in Vorsprünge des Bohrrohrs einzugreifen.Good handleability of the connecting device according to the invention is achieved when the axial locking element has projections which are configured to engage in depressions of the drill pipe in the axial locking position or if the axial locking element has recesses configured to engage in projections of the drill pipe in the axial locking position.
Bei einer platzsparenden und mechanisch hochverlässlichen Ausführungsform der erfindungsgemäßen Verbindungsvorrichtung ist das Axialverriegelungselement als Klemmhülse ausgebildet, die das Axialführungselement umgibt.In a space-saving and mechanically highly reliable embodiment of the connecting device according to the invention the Axialverriegelungselement is designed as a clamping sleeve which surrounds the axial guide element.
Um unabsichtliches Lösen der Verbindung mit dem Bohrrohr zu verhindern, kann die Verbindungsvorrichtung, vorzugsweise mittels Federn, in die Axialverriegelungsstellung vorgespannt sein.In order to prevent inadvertent release of the connection with the drill pipe, the connecting device, preferably by means of springs, can be biased into the axial locking position.
Für eine besonders hohe Verlässlichkeit und schnelle Herstellung der elektrischen Verbindung ist in einer bevorzugten Ausführungsform der erfindungsgemäßen Verbindungsvorrichtung ein drehbarer Außenkörper vorgesehen, in dem die elektrischen Anschlüsse so konfiguriert sind, dass sie durch Drehbewegung des Außenkörpers mit den elektrischen Anschlüssen des Bohrrohrs in Kontakt bringbar sind. Das Vorsehen von Drehgriffen erleichtert die Drehung der Verbindungsvorrichtung für das Bedienpersonal. Das Vorsehen von Axialgriffen vereinfacht allgemein die manuelle Führung der Verbindungsvorrichtung. In einer bevorzugten Ausgestaltung der Erfindung sind der Außenkörper und das Axialverriegelungselement in Bezug aufeinander axial im Wesentlichen starr, aber drehbar verbunden. Dabei kann die Verbindung mittels eines Zwischenelements realisiert sein, das axial starr mit dem Axialverriegelungselement verbunden ist und an seiner Außenfläche ein Außengewinde aufweist, auf das drehbar ein Innengewinde des Außenkörpers geschraubt ist. Das Axialverriegelungselement und/oder das Zwischenelement können durch ein Drehsperrelement gegen Verdrehen in Bezug auf das Axialführungselement gesichert werden. Alternativ dazu kann das Zwischenelement Drehsperrelemente zum Eingriff in das Bohrrohr aufweisen.For a particularly high reliability and rapid production of the electrical connection, a rotatable outer body is provided in a preferred embodiment of the connecting device according to the invention, in which the electrical connections are configured such that they can be brought into contact with the electrical connections of the drill pipe by rotational movement of the outer body. The provision of rotary handles facilitates the rotation of the connecting device for the operator. The provision of axial handles generally facilitates manual guidance of the connector. In a preferred embodiment of the invention, the outer body and the Axialverriegelungselement axially with respect to each other are substantially rigid, but rotatably connected. In this case, the connection can be realized by means of an intermediate element which is axially rigidly connected to the Axialverriegelungselement and on its outer surface has an external thread on which an inner thread of the outer body is rotatably screwed. The Axialverriegelungselement and / or the intermediate element can be secured by a rotary locking element against rotation with respect to the Axialführungselement. Alternatively, the intermediate element may comprise anti-rotation elements for engaging the drill pipe.
Für eine automatische oder zumindest halbautomatische Verbindung der Verbindungsvorrichtung mit einem Bohrrohr ist vorgesehen, dass der Außenkörper mittels eines Motors und optional eines Getriebes drehbar ist, wobei die Verbindungsvorrichtung vorzugsweise mit Aktuatoren zur automatischen Zufuhr zum und Wegfuhr vom Bohrrohr ausgestattet ist.For an automatic or at least semi-automatic connection of the connecting device with a drill pipe is provided that the outer body is rotatable by means of a motor and optionally a gear, wherein the connecting device is preferably equipped with actuators for automatic supply to and removal from the drill pipe.
Aus Sicherheitsgründen wird weiters ein Kontaktdetektorschalter vorgeschlagen, der detektiert, ob die elektrischen Anschlüsse der Verbindungsvorrichtung mit den elektrischen Anschlüssen des Bohrrohrs in Kontakt sind.For safety reasons, a contact detector switch is further proposed, which detects whether the electrical connections of the connecting device with the electrical connections of the drill pipe in contact.
Um zu verhindern, dass sich die elektrischen Leitungen zu sehr verwinden und dadurch brechen oder ihre Isolierung beschädigt wird, sieht die Erfindung auch vor, dass die zumindest eine elektrische Leitung mittels einer Drehausgleichsvorrichtung in einem Kabelstrang aus der Verbindungsvorrichtung herausgeführt ist.In order to prevent that the electrical lines too much twist and break or their insulation is damaged, the invention also provides that the at least one electrical line is led out by means of a Drehausgleichsvorrichtung in a harness from the connecting device.
Um beispielsweise an gelagerten Bohrrohren Messungen durchzuführen, ist es zweckmäßig, die erfindungsgemäße Verbindungsvorrichtung als Handgerät auszubilden, wobei an die zumindest eine elektrische Daten- und/oder Versorgungsleitung zumindest ein Gerät zum Ein- und Ausspeisen von Daten-, Status- und/oder Prüfsignalen und zur Auswertung von ausgespeisten Signalen angeschlossen ist, wobei das Gerät vorzugsweise ein Benutzerinterface aufweist.In order to carry out measurements on mounted drill pipes, for example, it is expedient to design the connection device according to the invention as a handheld device, wherein at least one device for inputting and outputting data, status and / or test signals and at least one electrical data and / or supply line for the evaluation of output signals is connected, the device preferably has a user interface.

Das Axialverriegelungselement 33 dient dazu, die Verbindungsvorrichtung 2 in Axialrichtung im Bohrrohr zu fixieren. Zu diesem Zweck sind das Axialführungselement 32 und das Axialverriegelungselement 33 relativ zueinander zwischen einer Axialverriegelungsstellung und einer Freigabestellung axial verlagerbar, wobei das Axialverriegelungselement 33 in seinem vorderen Bereich in eine Vielzahl von elastisch radial beweglichen Zungen 33b unterteilt ist, die an ihren freien Enden Vorsprünge 33a zum Ineinandergreifen mit dem Bohrrohr aufweisen. In der Axialverriegelungsstellung sind die Zungen 33b radial ausgefahren, in der Freigabestellung radial eingezogen, wie weiter unten im Detail erläutert wird. Das Axialführungselement 32 weist zwei durch einen stegförmigen Abschnitt 32b voneinander getrennte Vertiefungen in Form von Umfangsnuten 32a, 32c auf, die in zwei unterschiedlichen Freigabestellungen die Vorsprünge 33a des Axialverriegelungselements 33 aufnehmen.The
Das Axialverriegelungselement 33 ist in Bezug auf das Zwischenelement 34 axial starr montiert, so dass die Axialbewegung des Axialverriegelungselements 33 und des Zwischenelements 34 gemeinsam erfolgen, wodurch das Zwischenelement 34 nicht die radiale Bewegung der Zungen 33b behindern kann. Mittels eines Sägezahngewindes 37, umfassend ein Außengewinde 34c auf der Umfangsfläche des Zwischenelements 34 und ein Innengewinde 31a auf der Innenfläche des Außenkörpers 31, sind das Zwischenelement 34 und der Außenkörper 31 so miteinander verbunden, dass das Zwischenelement 34, das Axialverriegelungselement 33 und der Außenkörper 31 gemeinsam axial in Bezug auf das Axialführungselement 32 bewegt werden, wenn der Außenkörper 31 axial bewegt wird. Bei einer Drehbewegung des Außenkörpers 31 in Bezug auf das Axialverriegelungselement 33 ist der Außenkörper 31 jedoch axial in Bezug auf das Axialverriegelungselement 33 beweglich. Mittels zweier Federn 36 wird die Anordnung aus Zwischenelement 34, Axialverriegelungselement 33 und Außenkörper 31 in eine solche axiale Stellung gegenüber dem Axialführungselement 32 vorgespannt, dass sich die Verbindungsvorrichtung 2 in der Verriegelungsstellung befindet, in der die Vorsprünge 33a des Axialverriegelungselements 33 auf dem Stegabschnitt 32b des Axialführungselements 32 aufliegen. Die beiden Federn 36 üben von entgegengesetzten Richtungen jeweils gleiche Federkräfte aus, wodurch sich ein Kräftegleichgewicht einstellt, das die relative Axialstellung ergibt.The
Das Zwischenelement 34 dient zur radialen Fixierung der Verbindungsvorrichtung 2 im Bohrrohr. Dazu weist das Zwischenelement 34 an seiner vorderen Stirnfläche eine Abfolge an Vorsprüngen 34a und Vertiefungen 34b auf, die mit gegengleich geformten Vertiefungen und Vorsprüngen einer Schutzhülse im Bohrrohr ineinandergreifen. Um zu verhindern, dass sich das Axialverriegelungselement 33 und das Zwischenelement 34 in Bezug auf das Axialführungselement 32 verdrehen, ist ein Drehblockierstift 43 vorgesehen. Durch diese Konstruktion sind im Verbindungszustand zwischen der Verbindungsvorrichtung 2 und dem Bohrrohr das Axialverriegelungselement 33 und das Zwischenelement 34 radial und axial in Bezug auf das Bohrrohr fixiert.The
Nachfolgend wird anhand der
Nun wird mittels der Drehgriffe 38 der Außenkörper 31 der Verbindungsvorrichtung 2 gedreht, so dass die elektrischen Anschlüsse 35 (Buchse) der Verbindungsvorrichtung 2 mit den elektrischen Anschlüssen 73 (elektrische Kontaktstifte) des Bohrrohrs 6 axial in Ausrichtung gelangen, siehe
Um die Verbindung zwischen dem Bohrrohr 6 und der Verbindungsvorrichtung 2 zu lösen, werden die oben beschriebenen Vorgänge in umgekehrter Reihenfolge vorgenommen. Das heißt, dass zunächst durch Drehung des Außenkörpers 31 in die Gegenrichtung seine axiale Fixierung gelöst werden muss. Durch die Lösung der axialen Fixierung des Außenkörpers erfolgt eine Unterbrechung des galvanischen Kontakts der elektrischen Anschlüsse 35, 73. Durch Ziehen am Axialgriff 39 bewegt sich das Axialführungselement 32 axial in Bezug auf das Axialverriegelungselement 33 nach außen, da das Axialverriegelungselement 33 an einer Axialbewegung gehindert ist, weil seine Vorsprünge 33a gegen die Nase 72a des Verbindungselements 72 des Bohrrohrs stoßen. Durch die Relativverlagerung zwischen Axialführungselement 32 und Axialverriegelungselement 33 gelangt die erste Umfangsnut 32a des Axialführungselements 32 in Ausrichtung mit den Vorsprüngen 33a des Axialverriegelungselements 33, siehe
Die bisher beschriebene Ausführungsform der erfindungsgemäßen Verbindungsvorrichtung 2 ist für die manuelle Bedienung durch Bedienpersonal an der Bohranlage vorgesehen. Es ist jedoch auch möglich, die Verbindungsvorrichtung 2 für den halbautomatischen oder vollautomatischen Betrieb auszurüsten.The previously described embodiment of the connecting
