The proportions of volume flux in pores of different sizes.
The histograms are the proportions of pore volume of pores with different sizes. (a) Shale digital rock. The curve of Kn→0 is obtained without considering microscale effect, while the other four curves are obtained at 373 K under the following pressures: 20.0 MPa, 5.0 MPa, 2.0 MPa and 0.5 MPa. (b) Sandstone digital rock. The curve of Kn→0 is obtained without considering microscale effect, while the other four curves are obtained under the following resolutions: 78.0 nm/pixel, 39.0 nm/pixel, 11.0 nm/pixel and 3.9 nm/pixel.
