双河油田已进入开发后期 ,为了精确预测层内潜力分布状况 ,解剖更小级别的储层非均质单元的分布 ,提出了储层渗流单元分析法。研究表明 ,双河油田储层可划分出 4种渗流单元类型 ,渗流单元与成因砂体之间的关系不是简单的对应关系 ,平面上渗流单元分布很复杂 ,表现为极强的非均质性。储层渗流单元模型可应用于数值模拟网格划分和定性预测剩余油的分布 ,从而大大提高剩余油分布预测的精度和工作效率
Shuanghe Oilfield has entered the late stage of development. In order to accurately predict the potential distribution in the reservoir and dissect the distribution of reservoir heterogeneity at a smaller level, a seepage unit analysis method of reservoir is proposed. The results show that four kinds of seepage unit types can be distinguished in Shuanghe oilfield. The relationship between seepage units and genetic sand bodies is not a simple correspondence. The distribution of seepage units in the plane is very complicated, showing extremely strong heterogeneity . The reservoir seepage unit model can be applied to numerical simulation of meshing and qualitative prediction of the remaining oil distribution, thus greatly improving the accuracy and efficiency of the remaining oil distribution prediction
