Pore Structure Characteristics, Genesis, and Its Controlling Effect on Gas Migration of Quaternary Mudstone Reservoir in Qaidam Basin

Figure 13

Plots showing the relationship between pore structure and rigid mineral content. (a, c) Macropore pore volume is positively correlated with quartz and feldspar; (b, d) mesopore specific surface area is negatively correlated with quartz and feldspar; (e) macropore pore volume is negatively correlated with carbonate; (f) mesopore specific surface area has a weak positive correlation with carbonate.
