- Scope
- This standard specifies the basic principles, measurement methods, data processing and reporting format for measuring gas-water relative permeability. This standard includes two determination methods: steady-state method and non-steady-state method. The steady-state method is suitable for measuring the gas-water relative permeability of cylindrical rock samples with a permeability range of (0.500~1000)×10^(-3)μm^(2); the unsteady-state method is suitable for measuring the permeability greater than 0.0100 Gas-water relative permeability of ×10^(-3)μm^(2) cylindrical rock sample.
