Numerical prediction of saturated permeability tensor of a woven fabric for use in the fluid simulation of liquid composite molding;

Finite flement simulation of anisotropic reservoir considering full permeability tensor

Based on the equivalence concept, a method has been developed to calculate the equivalent permeability tensor and deformation parameters in fractured sandstone reservoir, and an equivalent continuum model has been established for reservoir seepage flow and deformation.

The calculation process of permeability coefficient tensor and synthetic permeability coefficient of the fractured rock mass were introduced in detail.

The permeability coefficient tensors of rock mass are calculated by the data of the dominant sets of joints or fractures and their distribution parameters statistically obtained from the many prospecting tunnels, and modified by the data of consolidation grouting test (including water pressuring test) in the left abutment.
