摘　　要：水驱油藏油井生产过程中,当井底流动压力低于饱和压力时,天然气会从原油中析出,油井产量将受到很大影响,主要因素包括油藏的渗透率和油的相对渗透率的改变,以及原油地下粘度和地下体积系数的变化。通过原油流动系数与流动压力之间的二项式关系,建立了油藏在饱和和未饱和情形下的油井流入动态方程,并建立了新的油井流入动态方程的通式。In the exploiting oil reservoir by water drive, dissolved gas will separate out from oil after the flow pressure under the bubble point pressure and the production of oil well is influenced greatly. The factors include change of oil reservoirs permeability and oil s relative permeability, and change of crude oil's subterranean viscosity and subterranean formation volume factor. By binomial relationship between crude oil s mobility-thickness product and flow pressure, the inflow performance relationship of saturated and not saturated oil reservoirs' wells has been founded, and the general inflow performance relationship also has been founded.
