1. a kind of shale structure characterization methods characterized by comprisingFirst shale samples to be measured are subjected to micron CT scan, obtain the first three-dimensional data of first shale samples to be measuredBody;

  • Second shale samples to be measured are subjected to nanometer CT scan, obtain the second three-dimensional data of second shale samples to be measuredBody;

    According to first 3D data volume and second 3D data volume, the hole of the described first shale samples to be measured is determinedGap-fracture spaces distribution;

    The hole of first shale samples to be measured is determined according to the hole of the described first shale samples to be measured-fracture spaces distributionGap-fracture connectivity feature;

    Wherein, the described second shale samples to be measured are a part of the described first shale samples to be measured.
