X-ray Imaging Of A Fractured Oil Shale Sample During Heating

摘要

1. Modified INL's high temperature x-ray CT permeameter to evaluate vertical fracture aperture deformation under pre-retort conditions 2. Validated image processing technique with a phantom 2.1 ～30 um aperture resolution 3. Conducted low temperature (200 °C) study in oil shale 3.1 Single axial fracture 3.2 Aperture decreased with increasing temperature (permeability decreased) 3.3 Hysteretic behavior observed 3.4 Monitoring data correlated well with x-ray image analyses.
