摘　　要：本文从渗流力学角度对Logistic产量递减方程进行了论证,并给出了其标准式,使得这一适用于低粘度的水驱油田的产量递减方程更具理论依据。这样,一旦确定了油相标准化相对渗透率关系式为K_(ro((?)wd)=A+Bexp(CSWd),即可确定油田产量递减方程符合Logistic产量递减,同时也可确定其初始递减率并对产量进行趋势预测。经实例验证,方法可行、可靠。In this paper, the Logistic production decreasing function is demonstrated from the percolationg mechanics aspect, and a standard equation is presented, which forms more concrete theoretical base for the production decreasing function adapted to low viscosity and water drive oil field. Thus, as soon as the standard oil relative permeability equation is confirmed to satisfy Kn>(swd) = A+Bexp(CSwd), the production decreasing function can be affirmed to satisfy Logistic production decline, and at the same time the initial decline rate can be calculated and predict the production tendency. Case history verification shows that the method is feasible and reliable.
