摘要
从相对渗透率曲线和物质平衡原理出发导出了双曲型、调和型和指数型产量递减方程式，论证了水驱油藏产量递减方程主要取决于油相相对渗透率曲线特性并进行了有关讨论。
Based on relative permeability curve and material balance principle, hyperbolic, harmonic and exponential decline equations have been derived and the fact that decline equation on wa-ter-drive reservoir mainly depends on the characteristic of relative permeability curve for oilphase has been demonstrated,and also some other related discussions have beed made in thispaper. The results provided important fundamentals for the further understanding and cor-rect use of production decline equations.
