The fractal dimension calculated from mercury injection curves is used for quantitative characterization of heterogeneity in micro-porosity structure of reservoir.

With mercury injection capillary curve and thin section, hole porosity and throats with their shapes and distributions are studied and porosity structure model is set up.

When the process was done, the porosity-a measure of the empty space in the structure-was about 94 percent, just below the theoretical limit of 96 percent.

当整个过程完成后，空隙度达到94%，刚好低于96%的极限水平。

This porosity could be in the form of micro porosity (think pumice) or macro porosity (think large voids and a rubble pile structure) or probably even both.
