童宪章提出的水驱特征曲线变换公式简单，参数求解容易，反映了不同含水上升规律的特性，在预测油田产油量、可采储量等方面起到了重要作用，但其只适用于中高渗透油藏。在此基础上，根据油水两相渗流理论推导出了改进的水驱特征曲线，此公式体现了不同相渗特征决定着不同的水驱特征曲线，使已有水驱特征曲线更加完善、更具理论依据，得到了适用于计算低渗透及中高渗透油藏水驱地质储量的通式。利用两种公式分别计算了某一油田的水驱地质储量，结果表明：用改进的水驱特征公式计算的水驱地质储量，精度更高，为油田高含水阶段准确估算水驱储量提出了新的思路，相对于目前国内常用的统计法，节省了大量的时间，对指导矿场生产实践具有重要意义。

A new generalized water drive curve proposed by Tong Xianzhang is of simple shape,and reflects different laws of water cut and it is easy to obtain its parameters. This water driving curve has played an important role in predicting oil production and recoverable reserves. On this basis,further studies were made and improved beta-water drive curves were derived according to the two-phase seepage theory. The improved water drive curves show that seepage characteristic determined the water drive curves. By using the improved water drive characteristic formula more accurate results can be obtained in geological reserves calculation. The improve water drive curve provides a new method for more accurate water-flooding reserves calculation in high water cut stage and has important practical significance to mine production pratice.
