By an expended derivation of Type C water drive curve, it can be used to predict not only recoverable reserves, movable oil in place, water_cut and ultimate volumetric sweep factor, but also recovery efficiency, displacement efficiency and residual oil saturation in water drive oilfields.
对丙型水驱曲线进行了扩展推导 ,使其不仅可以预测水驱油田的可采储量、可动油储量、含水率和最终体积波及系数 ,而且可以预测水驱油田的采收率、驱油效率和残余油饱和度。
