Abstract
Rohrelement für ein Bohr- oder Förderrohrgestänge, mit einem Außenrohr aus elektrisch leitfähigem Material, gekennzeichnet durch einen durch das Außenrohr hindurchgeführten elektrischen Leiter, der gegenüber dem Außenrohr elektrisch isoliert ist.Pipe element for a drill pipe or production pipe string, with an outer pipe made of electrically conductive material, characterized by an electrical conductor which is passed through the outer pipe and is electrically insulated from the outer pipe.
Description
Die Erfindung betrifft ein Rohrelement für ein Bohr- oder Förderrohrgestänge, mit einem Außenrohr aus elektrisch leitfähigem Material. Außerdem betrifft die Erfindung ein Bohr- oder Fördervorrichtung, mit einer Mehrzahl von zu einem Gestänge verbundenen Rohrelementen.The invention relates to a pipe element for a drilling or production pipe string, with an outer tube made of electrically conductive material. Moreover, the invention relates to a drilling or conveying device, with a plurality of pipe elements connected to a linkage.
Tiefbohrungen werden mit derartigen Rohrelementen bzw. Gestängen durchgeführt, um z. B. Gas-, Wasser- oder Erdölhorizonte zu erschließen. Technische Probleme bereitet das genaue Auffinden und Erreichen eines bestimmten Horizonts mit dem Bohrgestänge. Problematisch ist außerdem die fortlaufende Überwachung des Zustands des Bohrlochs und der Qualität des zu gewinnenden Rohstoffes während der Förderung.Deep holes are performed with such pipe elements or poles to z. B. gas, water or petroleum horizons. Technical problems are the exact finding and reaching of a certain horizon with the drill string. Another problem is the continuous monitoring of the status of the well and the quality of the raw material to be extracted during production.
Aufgabe der Erfindung ist es, ein Bohr- oder Förderrohrgestänge bereitzustellen, das eine elektrische Energieversorgung von in das Gestänge eingegliederten elektrisch betriebenen Einrichtungen und eine Datenübertragung zwischen über und unter Tage ermöglicht.The object of the invention is to provide a drilling or production pipe string, which allows an electrical power supply of incorporated into the linkage electrically operated facilities and data transmission between above and below ground.
Diese Aufgabe wird durch ein Rohrelement nach Anspruch 1 und durch eine Bohr- oder Fördervorrichtung nach Anspruch 8 gelöst.This object is achieved by a tubular element according to
Bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Preferred embodiments of the invention are the subject of the dependent claims.
Das erfindungsgemäße Rohrelement, das für ein Bohr- oder auch für ein Förderrohrgestänge vorgesehen sein kann, weist ein Außenrohr aus elektrisch leitfähigem Material auf. Durch das Außenrohr ist ein elektrischer Leiter geführt, der gegenüber dem Außenrohr elektrisch isoliert ist. Dieser elektrische Leiter dient zur elektrischen Energieversorgung von in das Gestänge eingegliederten elektrisch betriebenen Einrichtungen und zur Datenübertragung zwischen über und unter Tage über einen aus gleichartigen Rohrelementen zusammengesetztes Gestänge. Bevorzugt ist der elektrische Leiter ein Innenrohr aus elektrisch leitfähigem Material, wobei das Innenrohr zu dem Außenrohr konzentrisch angeordnet ist, mit einem ringspaltförmigen Hohlraum zwischen Innenrohr und Außenrohr. Über Innen- und Außenrohr ist eine zweipolige Energie- und/oder Datenübertragung möglich. Das Innenrohr ist über den ringspaltförmigen Hohlraum von dem Außenrohr getrennt. Über den größten Teil der Längserstreckung des Rohrelements bilden Außen- und Innenrohr keinen Verbund. Die von dem Gestänge aufzunehmenden mechanischen Belastungen können somit im Wesentlichen von dem Außenrohr getragen werden. Das Innenrohr hat keine mechanisch tragende Funktion. Außerdem sorgt der ringspaltförmige Hohlraum, der gegenüber der Umgebung und gegenüber dem Rohrinneren abgedichtet sein sollte, für einen geringen elektrischen Wellenwiderstand, was positiv für die Datenübertragung (beispielweise nach dem Trägerfrequenzprinzip) über große Distanzen ist. Die Spaltbreite des ringspaltförmigen Hohlraums sollte wenigstens 1 mm, vorzugsweise wenigstens 5 mm, höchst bevorzugt wenigstens 1 cm betragen. Das Innenrohr kann an dem Außenrohr zumindest in dessen gegenüberliegenden Endbereichen fixiert sein.The pipe element according to the invention, which may be provided for a drilling or for a conveyor pipe string, has an outer tube made of electrically conductive material. Through the outer tube, an electrical conductor is guided, which is electrically insulated from the outer tube. This electrical conductor is used for electrical power supply of incorporated into the linkage electrically operated devices and for data transmission between above and below ground via a composite of similar pipe elements linkage. Preferably, the electrical conductor is an inner tube of electrically conductive material, wherein the inner tube is arranged concentrically to the outer tube, with an annular gap-shaped cavity between the inner tube and outer tube. About inner and outer tube a bipolar energy and / or data transmission is possible. The inner tube is separated from the outer tube via the annular gap-shaped cavity. Over the greater part of the longitudinal extent of the tubular element outer and inner tube form no bond. The mechanical loads to be absorbed by the linkage can thus be carried substantially by the outer tube. The inner tube has no mechanical bearing function. In addition, the annular gap-shaped cavity, which should be sealed from the environment and from the inside of the tube, ensures low electrical characteristic impedance, which is positive for the data transmission (for example according to the carrier frequency principle) over long distances. The gap width of the annular gap-shaped cavity should be at least 1 mm, preferably at least 5 mm, most preferably at least 1 cm. The inner tube may be fixed to the outer tube at least in its opposite end regions.
Wie ein übliches Rohrelement für ein Bohr- oder Förderrohr kann das Außenrohr an seinen Enden Gewindeanschlüsse aufweist, über welche gleichartige Rohrelemente miteinander lösbar verbindbar sind. Im Bereich dieser Gewindeanschlüsse können Elektroden angeordnet sein, die einen elektrischen Kontakt zwischen den elektrischen Leitern miteinander verbundener gleichartiger Rohrelemente herstellen. Die Elektroden können z. B. als zur Längsmittelachse des Rohrelements konzentrische Ringelektroden ausgebildet sein. Das Innenrohr sollte zumindest an seiner Innenseite eine Beschichtung aus elektrisch Isolierendem Material aufweist, damit das Rohrinnere von Fluid (z. B. Wasser, Gas, Erdöl, Bohrspülung) durchströmt werden kann.Like a conventional tubular element for a drilling or production pipe, the outer pipe can have threaded connections at its ends, via which similar pipe elements can be detachably connected to one another. In the region of these threaded connections, electrodes can be arranged which produce an electrical contact between the electrical conductors of interconnected similar tube elements. The electrodes can z. B. be formed as concentric to the longitudinal central axis of the tubular element ring electrodes. The inner tube should have at least on its inner side a coating of electrically insulating material, so that the tube interior can be traversed by fluid (eg water, gas, petroleum, drilling mud).

Prinzipiell besteht die Möglichkeit, im Inneren der Messvorrichtung jegliche Art von Messsensorik mit zugehöriger Elektronik unterzubringen. Die Sensorik und Elektronikkomponenten können auf einer geeigneten Montageplatte montiert werden, die mittels eines steuerbaren hydraulischen Dämpfersystems in Ruhe gehalten wird. Die Sensoren können Qualitäts- und Quantitätssensoren sein, die zur Überwachung der Spülung sowie des Bohrlochringraum genutzt werden. Die gewonnenen Daten können über das Bohrgestänge
Zur Eingliederung in den erfindungsgemäßen Bohr- oder Förderstrang (über die Gewindeanschlüsse der Rohrelemente) eignet sich ein standardisiertes Modul, das in seinem Inneren eine Kapsel zum Einbau beliebiger Sensoren oder anderer Einrichtungen aufweist. Der Durchlass für die Bohrspülung bzw. für den zu fördernden Rohstoff kann im Eingangsbereich des Moduls nach Außen in einen ringspaltförmigen Kanal zwischen Kapselaußenwand und Innenwand des Modulgehäuses umgeleitet werden. Die Kapsel kann auf diese Weise ausreichend groß dimensioniert werden, um beliebige Komponenten einzubauen, ohne die Bohr- oder Förderfunktionalität einzuschränken. Am Ausgang des Moduls wird die Spülung bzw. das zu fördernde Medium wieder zurück nach Innen geleitet, und zwar in das Innenrohr
