Shale structure reconstruction by X-ray computerized tomography based on total variation regularization
Abstract
The microstructure knowledge of shale is the basis of shale gas exploration and production. In this paper, we applied parallel X-ray computerized tomography technology rather than conventional surface-based observation methods to recover the shale structure non-destructively. In order to avoid the X-ray hardening, we used the synchrotron radiation source to acquire the projection data. Total variation regularization method was applied to suppress the noise effect and improve the image contrast, and primary-dual algorithm was used to solve it. Experimental tests show that the proposed approach is a feasible and efficient method to reconstruct the shale microstructure precisely and accurately.
