Definitions

  • the invention is based on a method for detecting cores.
  • Core cores are usually single after completion of a well
  • 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.
  • 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.
  • 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.
  • 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

  • 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.
  • 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

  • All images of the core sections are assembled into an image of the complete core. This allows a visual representation of the entire core.

  • 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.

Abstract

L'invention concerne un procédé d'enregistrement de carottes comportant les étapes suivantes: ordonner des segments de carottes individuels en fonction d'une échelle de référence ou d'un cadre de référence avec des mesures connues, élaborer des images des segments de carottes individuels avec l'échelle de référence ou le cadre de référence, assembler les images des segments de carottes individuels pour former une représentation à l'échelle de l'ensemble de la carotte, saisir les propriétés physiques et/ou chimiques en différentes positions de la carotte, associer les propriétés physiques et/ou chimiques à la représentation de la carotte aux emplacements correspondants aux positions associées.
