説明
Permeability of sedimentary rock obtained as a core sample from the deep underground was measured in the laboratory. To evaluate permeability anisotropy, i. e. the difference between horizontal and vertical permeability in the bedding plane, permeability of samples shaped from the core in the parallel or orthogonal direction were determined. Consequently, it was indicated that the permeability in the direction parallel to the bedding plane was larger than that in the direction perpendicular to it. An influence on the permeability anisotropy evaluation with different method of horizontal and vertical sample acquisition was examined. As a result, it was considered that permeability anisotropy measured by using the same sample was evaluated more appropriately than that measured by using two samples obtained from neighborhood for fine sandstone and mudstone. A relationship between porosity or seismic velocity and permeability or permeability anisotropy was also examined to be revealed that permeability and shear wave velocity were rather related, and that permeability anisotropy had little correlation with porosity or seismic velocity.
