AUTOMATED WORKFLOW FOR 3D CORE DIGITAL MODELING FROM COMPUTERIZED TOMOGRAPHY SCANNER (CTS) IMAGES

摘要

Computer-implemented methods, systems, and non-transitory computer-readable medium having computer program stored therein are provided to enhance the accuracy and efficiency of modeling a core sample from images of two-dimensional transverse sections of a core sample. Embodiments of the invention include, for example, image registering a plurality of images of transverse sections of a core sample to produce aligned transverse sections by approximating the circular location of the boundary of the transverse section and aligning the images based on center points of the approximated circles. Embodiments can further include, for example, performing a saw cut correction on the aligned transverse section images to adjust the images for the slab cut, generating a three-dimensional simulated model of the core sampling using or more of the saw cut line corrected images, and generating a three-dimensional simulated model of the internal composition of a borehole related to the core sample using multipoint statistics calculations.

主权项

1. A computer-implemented method to process two-dimensional images of a core sample, the method comprising:
approximating, using one or more computer processors, a circular boundary for each of a plurality of polygon shaped images of a substantially cylindrical core sample, each image having a representation of a different transverse section of the core sample and a background that substantially surrounds the representation; selecting, using one or more computer processors, a center point of each of the approximated circular boundaries of the images to define a reference point; determining, using one or more computer processors, an imaginary line passing through the reference point of a first end of the representation of one of the plurality of transverse sections and extending substantially perpendicular to the plane of the representation of the first end to thereby define a simulated axis; and aligning, using one or more computer processors, each of the representations of transverse sections along the simulated axis, each reference point being positioned on the simulation axis.
