Summary
This standard specifies the determination of the two-phase relative permeability rock the basic principles of measurement and calculation methods as well as the technical specifications of measuring instruments. This standard applies to cemented sandstone samples in two-phase relative permeability measurement, other types of rock samples may refer to. This standard includes two kinds of steady and unsteady relative permeability measurement method. Steady state oil water relative permeability measurement for air permeability greater than 50mD rock samples, steady state gas Determination of water relative permeability ranges for air permeability of the rock sample 0. 5mD ~ 1000mD, non- steady state method oil water and gas oil relative permeability measurement for air permeability of the rock sample is greater than 5mD, non- steady state gas Determination of water relative permeability greater than 0. 01mD for air permeability of rock samples.
