Abstract

Abstract: The unstability of unsteady relative permeability curves was quoted and discussed. The conditions suitable for steady and unsteady permeability curves were studied and therefore. reference for choosing relative permeability curves in the numeric simulation of oil reservoirs were provided.

Key words: Relative permeability curve, Steady state, Unsteady state, Unstability, Unsteady degree, Stability number
