摘　　要：目的：准确认识油田动态变化规律，为油田的开发设计、开发调整及开发分析提供重要依据。方法：根据建立的河流相储层渗透率平面非均质抽象模型以及河流相储层的典型参数，考虑油水粘度比、油水井数比、井距不均匀系数、井网密度、平面渗透率对数正态分布变异系数、概率50％处渗透率、油藏大小、断层边界、含水率共9个因素，进行27个方案的数值模拟。结果：经处理数值模拟结果，得出计算含水率1．0时的无困次采液指数JL1.0的回归公式以及无固次采液指数JL与含水率fw关系的典型通用公式。结论：计算实例表明通用公式计算结果符合油田实际。According to the established abstract model of permeability plane heterogeneous distributionand the typical pararneters, and considering 9 factors: oil-water viscosity ratio, producer-injector ratio, well spac-ing non-uniform coefficient, well density, vdriation coefficient of logarithmic normal distribution of plane perme-ability, Permeability of 50 % probability, size of reservoir, boundary of fault and water cut, the numerical simula-tion of 27 programrn was completed. Handling the results of numerical simulation, a regression formula for cal-culating dimensionless liquid preduction index JL1.0 at water cut fw = 1. 0 and a typical and general formula of di-mensionless liquid preduction index JL vs fw are obtained. An example shows that the calculating results by thetapical and general formula accord with the practical data of reservior.
