通常实验室会提供若干条各不相同的相对渗透率曲线,然后进行平均相对渗透率曲线的标准化处理,得到具有代表性的相对渗透率曲线。然而几乎没有学者将各方法的标准化结果与实际油田开采特征及油水运动规律相结合来评价这些方法的合理性。基于此,文中结合油田实际生产动态,从含水上升规律、驱油效率及采收率等3方面对各方法的标准化结果进行分析研究。结果表明,多条曲线平均标准化方法确定的油水相对渗透率曲线更符合实际油藏渗流特征。
Usually, the laboratory will provide several different relative permeability curves, and then normalize the average relative permeability curve to get the representative relative permeability curve. However, few scholars have evaluated the reasonableness of these methods by combining the standardized results of each method with the actual oilfield exploitation characteristics and the law of oil and water movement. Based on this, based on the actual production dynamics of the oilfield, the standardization results of each method are analyzed and studied from the aspect of water-bearing rise, oil displacement efficiency and oil recovery. The results show that the relative permeability curves of oil and water determined by the multiple curve normalization methods are more in line with the actual reservoir seepage characteristics.
