  • This paper took the sandstone reservoirs of Liaohe Oilfield ( Es1, Es3 ) as a case and elaborated howto establish functions between mercury injection pressure ( Pc) and mercury saturation ( SHg), then toconduct some geological applications of these functions. The results indicated that there exists a goodhyperbola relationship between Pc and SHg in the studied area. From these functions one can calculatethe capillary pressue. obtain the capillary pressure curves from porosity and permeability, and computethe permeability and permeability contribution at any SHg intervals.
