摘要
从矿场实用出发,介绍一种适用于新油田开发动态指标预测的水驱曲线数学模型。文中导出了应用相对渗透率曲线求极限含水时的含水上升率的公式,以及在已知边界值条件下反求数学模型的特征参数A、B、C值的计算式。简析了水驱曲线特征位A、B、C对曲线形态的影响,并对曲线类型的判别做了初步探讨。最后,用矿场开发试验区资料验证数学模型的可行性和精度都是较好的。
<ABSTRACT> A mathematical model of water drive curves suitable for developing new oilfields is presented from the point of view of field practice.The expression of incremental water cut can be derived from the solution of the limiting values of water cut for the relative permeability curve.The antireprcscntation of the characteristic parameters A, B and C under the known boundary conditions can be also given.The influence of these characteristic values A, B and C on the shape of the water drive curves is analysed, and the diagnostic types of these curves are preliminarily dis cussed. Finally, field data show that the modelis feasible and accurate.
