AbstractThe understanding of shale microstructure is the basis of shale gas exploration and development. The traditional detection method is based on the surface damage observation method. In this work, the synchrotron radiation technology of Shanghai Light Source is applied to nondestructive detection of shale structure to obtain projection data, which can avoid X-ray hardening. We use X-ray Computed Tomography (CT) technology to restore images, and propose an L1 norm + TV (total variation) constrained non-smooth regularization method to suppress noise and improve image contrast. Experiments show that this method is effective to reconstruct the microstructure of shale accurately.
