Abstract: Based on principle of the mass conservation, the mathematical model of oil-water two-phase transient flow was set up,after defined the oil-water two-phase pseudo-pressure function,the mathematical model was linearized. After obtaining solution of mathematical model, we derived the two-phase productivity equation of oil-water well with formation damage. Therefore,
the theory of transient inflow performance relationship curve for oil-water well was established. The transient inflow performance relationship curve of oil-water well could be calculated by the productivity equation. The research in this paper provided the theory supports for the performance analysis of oil-water well.

Key words: oil-water well, two-phase flow, mathematical model, productivity equation
