Impacts of Pore-Throat System on Fractal Characterization of Tight Sandstones

Figure 6

Correlation coefficients of the typical parameters related to pore-throat structures and fractal dimensions. Positive values mean positive relationships, while negative values represent a negative correlation. TR: threshold radius; MR: median radius; AR: average radius; MS: maximum mercury saturation; EW: efficiency of mercury withdrawal; SC: sorting coefficient; SK: skewness.
