将广义 Копытов预测模型和乙型水驱曲线方法有机的结合起来 ,得到了油田开发中后期——递减时期的一种预测水驱开发油田的含水率、产油量、产水量及其相应的累积产量随开发时间变化的方法 ,此方法克服了在水驱油田预测开发指标中二者所存在的局限性。 By combining the generalized Копытов forecasting model and the B type water flooding curve method, we get a prediction of the water cut, oil production, water production and its corresponding accumulation in the mid-late-descending period of oilfield development This method overcomes the limitations of both in predictive development of waterflooding fields.
