Three-dimensional digital rock image of fractured rock

Summary X-ray computed tomography technology can reveal the microscopic structure of the reservoir rock, but to fractured reservoir, it is very difficult to drill a characteristic rock sample with fracture because of the discontinuity of the rock. So it is hard to construct the digital rock image of fractured reservoir using X-ray computed tomography technology only. In this paper we propose a method to construct the three-dimensional digital rock image of rocks containing fracture.
