针对FZ油田中低渗、小断块油藏的特点,通过细分流动单元、沉积微相和储层建筑结构的研究,应用RMS随机建模软件,建立了油藏三维地质模型,应用数值模拟方法,预测了剩余油分布,在此基础上制定剩余油调整挖潜措施,矿场应用效果明显

According to the characteristic of the middle-lower penetrability block reservoir in FZ Oil Field, this article constructs a 3D geologic model through subdividing flow units, studying sedimentary micro-phase and reservoir architecture structure and using RMS random modeling technique. Through reservoir numerical simulation method, it forecasts the distribution rule of the residual oil. Finally it determines the measure of residual oil adjustment for potential seeking and the effect of reducing water cut and improving the recoverable reserves is obvious.
