依据数值模拟非均质地质模型的水驱油动态，建立了切合油水井生产实际的动态劈分方程。该方程考虑沉积相、渗透率级差、生产层段射开程度、井距等多项影响因素，计算井组、小层的孔隙体积注入倍数，以非稳定一维驱替的前缘推进方程为数学模型，利用分流量方程（曲线）计算井间驱替前缘含水饱和度，然后用插值法得到剩余油分布。经运用于文13北块，取得初步成功。该方法适用于小断块油藏，在微机上即可简便实现。
According to the numerical simulation of the dynamic of water flooding in heterogeneous geological model, the dynamic dynamic equation for splitting oil and water wells is established. This equation considers multiple influencing factors, such as sedimentary facies, permeability gradient, shooting interval of production interval and well spacing, and calculates the pore volume injection multiple of well group and sub-layer. The forward advancing equation with one-dimensional displacement is Mathematical model, the use of flow equations (curve) to calculate the cross-well waterfront displacement of water saturation, and then obtained by interpolation residual oil distribution. After being applied to Wen 13 North Block, preliminary success has been achieved. The method is suitable for small fault block reservoir and can be easily implemented on a microcomputer.
