Study of Single Fracture Seepage Characteristics of Fault-Filled Materials Based on CT Technology

In order to study the matrix loss process and skeleton seepage law in fracture of fault rock, three-dimensional model skeletal rock sample was obtained by CT scan, porous media established with different structural types natural fractures, flow rate pressure distribution FLUENT software simulation. The results show that: under conditions is approximately same, velocity increases continuously increase pressure; water directions channels same not exactly which caused microstructures pores. For distribution, it gradually decreases along direction seepage, for speed shows changing from large small then increasing.
