摘　　要：油藏经过长期注水冲刷以后,储层渗透率及油水运动规律发生明显变化,特别是进入特高含水期后,储层的这种变化特征以及夹层和高渗流带对剩余油的影响,是油藏数值模拟需要考虑的重要因素。通过对泥质、灰质、物性夹层参数进行分类赋值,并建立储层物性渗透率时变模型和不同含水阶段相对渗透率模型,实现高精度历史拟合和剩余油描述,为制定开发技术政策界限以及设计优化开发调整方案提供可靠依据。After a long time of washout by injected water, the reservoir permeability and movement disciplinarian of oil and water changed obviously. The variation characteristics of reservoirs and the effect on remaining oil of interlayer and high permeability zone is key factors that need to be considered in reservoir numerical simulation especially when entered the extra high water cut period.By classified valuation of muddy intercalation, gray interlayer and physical property interlayer and establishing time-varying model of reservoir physical permeability and phase permeability model of different water cut periods, high precision of history matching and remaining oil description have been achieved, and offered reliable basis for formulating production technology policy limitations and designing and optimizing the development adjustment schemes.
