Figure 7

The capillary curves of four samples used in the numerical simulation process. The -axis shows the injected mercury saturation, and the -axis shows the capillary pressure. Through simple conversion, the pressure can be converted to capillary pressure in the presence of gas-water two-phase fluid.
