B E S C H R E I B U N G DESCRIPTION
Die Erfindung geht aus von einem Verfahren zur Erfassung von Bohrkernen. Bohrkerne liegen nach dem Abschluss einer Bohrung in der Regel als einzelneThe invention is based on a method for detecting cores. Core cores are usually single after completion of a well
Bohrkernabschnitte vor, die zum Transport und zur Lagerung in Kisten mit vorgegebenen Maßen verpackt werden. Zu den einzelnen Abschnitten werden üblicherweise Untersuchungen durchgeführt um die physikalischen und/ oder chemischen Eigenschaften des Bohrkerns an verschiedenen Positionen zu bestimmen. Drill core sections, which are packed for transport and storage in boxes of specified dimensions. For the individual sections, investigations are usually carried out to determine the physical and / or chemical properties of the core at different positions.
Als nachteilig erweist sich, dass der Bohrkern nur in einzelne Abschnitte zerteilt vorliegt, die Aufbewahrung und die Archivierung der Bohrkerne aufgrund ihrer Größe aufwendig ist und die Darstellung der physikalischen und/ oder chemischen Eigenschaften der Bohrkerne erschwert ist. A disadvantage proves that the core is divided into individual sections, the storage and archiving of cores is complicated due to their size and the representation of the physical and / or chemical properties of the cores is difficult.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Erfassung von Bohrkernen zur Verfügung zu stellen, das die Archivierung der Bohrkerne erleichtert und die Darstellung der physikalischen und/ oder chemischen Eigenschaften der Bohrkerne vereinfacht und übersichtlicher macht. The invention has for its object to provide a method for detecting cores available that facilitates the archiving of cores and makes the representation of the physical and / or chemical properties of the cores simplified and clearer.
Diese Aufgabe wird durch das Verfahren mit den Merkmalen des Anspruchs 1 gelöst. Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, dass von den einzelnen Bohrkernabschnitten Bilder erzeugt werden, die einen Referenzmaßstab oder einen Referenzrahmen enthalten. Ein derartiger This object is achieved by the method having the features of claim 1. The method according to the invention is characterized in that images are generated by the individual drill core sections which contain a reference scale or a reference frame. Such a
Bestätigungskopiel Referenzrahmen kann beispielsweise eine bekannte Kiste sein, in der die einzelnen Bohrkernabschnitte zur Aufbewahrung angeordnet werden. Die Maße dieser Kisten sind bekannt. Ist die Kiste in dem Bild erkennbar, können unter Verwendung der Maße der Kiste die Maße des in der Kiste angeordneten Bohrkernabschnitts berechnet werden. Darüber hinaus besteht die Möglichkeit, bei der Aufnahme des Bildes einen Referenzmaßstab neben den Bohrkernabschnitten anzuordnen. Auch aus diesen bekannten Maßen des Referenzmaßstabs können die Maße des Bohrkernabschnitts bestimmt werden. Zu den Maßen des Bohrkernabschnitts zählen insbesondere seine Länge und sein Durchmesser. Insbesondere kann jeder Position eines Bohrkernabschnitts einBestätigungskopiel Reference frame may be, for example, a known box in which the individual drill core sections are arranged for storage. The dimensions of these boxes are known. If the box is visible in the image, the dimensions of the box of cores arranged in the box can be calculated using the dimensions of the box. In addition, it is possible to arrange a reference scale next to the drill core sections when taking the image. Also from these known measures of the reference scale, the dimensions of the drill core section can be determined. The dimensions of the drill core section include in particular its length and its diameter. In particular, any position of a drill core section can
Maß zugeordnet werden. Measure are assigned.
Einzelne Bohrkernabschnitte können unvollständig oder fragmentiert sein. Zur Erstellung eines Bildes werden die Bruchstücke oder Fragmente möglichst genau so angeordnet, wie sie in einem vollständigen Bohrkern vorliegen würden. Auch in diesem Fall kann jeder Position des Bohrkernabschnitts in dem Bild ein Maß zugeordnet werden. Individual drill core sections may be incomplete or fragmented. To create an image, the fragments or fragments are arranged as exactly as they would be in a complete core. Also in this case, a measure can be assigned to each position of the drill core section in the image.
Alle Bilder der Bohrkernabschnitte werden zu einem Abbild des vollständigen Bohrkerns zusammengesetzt. Dadurch ist eine visuelle Darstellung des kompletten Bohrkerns möglich. All images of the core sections are assembled into an image of the complete core. This allows a visual representation of the entire core.
Zu den einzelnen Bohrkernabschnitten werden physikalische und/ oder chemische Eigenschaften erfasst. Hierzu können die Bohrkernabschnitte an verschiedenen Positionen untersucht werden. Die dabei ermittelten Daten werden dem Abbild des Bohrkerns zugeordnet. Insbesondere werden die Daten denjenigen Stellen in dem Abbild des Bohrkerns zugeordnet, die der Position des Bohrkerns, an welcher die zugehörigen Messungen durchgeführt wurden, entspricht. Physical and / or chemical properties are recorded for the individual drill core sections. For this purpose, the core sections can be examined at different positions. The data thus obtained are assigned to the image of the drill core. In particular, the data is associated with those locations in the image of the core corresponding to the location of the core on which the associated measurements were taken.
Das Maßstabs-getreue Abbild des Bohrkerns mit den zugehörigen positionsabhängigen physikalischen und/ oder chemischen Daten liefert alle wesentlichen Daten des Bohrkerns in einer visuellen Darstellung. Auf diese Weise wird die Archivierung eines Bohrkerns stark vereinfacht. Es ist nicht zwingend notwendig, die Bohrkerne vollständig aufzubewahren, da alle Informationen in den zusammengestellten Daten enthalten sind. Ferner wird die Darstellung der physikalischen und/ oder chemischen Eigenschaften eines Bohrkerns übersichtlicher gestaltet und vereinfacht. The scale-true image of the core with the associated position-dependent physical and / or chemical data provides all essential data of the core in a visual representation. In this way, the archiving of a core is greatly simplified. It is not absolutely necessary to keep the cores completely, since all information is contained in the compiled data. Furthermore, the representation of the physical and / or chemical properties of a drill core is made clearer and simplified.
Nach einer vorteilhaften Ausgestaltung der Erfindung wird der Referenzmaßstab oder der Referenzrahmen in das Abbild aufgenommen. Die für die Maßstabs-getreue Darstellung verwendete Referenz ist damit in dem Abbild erkennbar. According to an advantageous embodiment of the invention, the reference scale or the reference frame is included in the image. The reference used for the true-to-scale representation is thus recognizable in the image.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung wird in das Abbild ein Maßstab mit einer metrischen Einheit aufgenommen, der vom Aussehen des Referenzmaßstabs oder des Referenzrahmens verschieden ist. Dabei kann es sich beispielsweise um ein in das Abbild eingeblendetes aßband handeln. According to a further advantageous embodiment of the invention, a scale is recorded in the image with a metric unit, which is different from the appearance of the reference scale or the reference frame. This may be, for example, an aßband displayed in the image.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung werden beim Zusammenfügen der Bilder geometrische Korrekturen durchgeführt. Dies ist insbesondere dann von Vorteil, wenn ein Bohrkernabschnitt fragmentiert ist und einzelne Fragmente fehlen. According to a further advantageous embodiment of the invention, geometric corrections are performed when joining the images. This is particularly advantageous when a core section is fragmented and individual fragments are missing.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung werden dem Abbild des Bohrkerns der Bohrort, die Bohrung betreffende Eigenschaften und/ oder die Bohrtiefe zugeordnet, According to a further advantageous embodiment of the invention, the image of the drill core the Bohrort, the hole related properties and / or the drilling depth are assigned
