STEAM-WATER RELATIVE PERMEABILITY BY THE CAPILLARY PRESSURE METHOD

摘要: Various capillary pressure techniques such as the Purcell, Burdine, Corey, and BrooksCorey methods were utilized to calculate steam-water relative permeabilities using measured data in both drainage imbibition processes. The calculated results compared experimental of permeability Berea sandstone. simultaneously. differences between Purcell model values almost negligible for water phase but not steam phase. insignificance effect tortuosity factor on wetting was revealed this case. by other models very close different expected. same calculation made nitrogen-water flow confirm observation flow. study showed that it would be possible useful method, especially
