Based on the abundant core data of oil sands in the Mackay river in Canada, the termination frequency of muddy interlayers was counted to predict the extension range of interlayers using a queuing theory model, and then the quantitative relationship between the thickness and extension length of muddy interlayer was established. An equivalent upscaling method of geologic model based on tortuous paths under the effects of muddy interlayer has been proposed. Single muddy interlayers in each coarse grid are tracked and identified, and the average length, width and proportion of muddy interlayer in each coarse grid are determined by using the geological connectivity tracing algorithm. The average fluid flow length of tortuous path under the influence of muddy interlayer is calculated. Based on the Darcy formula, the formula calculating average permeability in the coarsened grid is deduced to work out the permeability of equivalent coarsened grid. The comparison of coarsening results of the oil sand reservoir of Mackay River with actual development indexes shows that the equivalent upscaling method of muddy interlayer by tortuous path calculation can reflect the blocking effect of muddy interlayer very well, and better reflect the effects of geological condition on production.

基于加拿大麦凯河的大量油砂岩心数据，利用排队论模型计算了泥质夹层的终止频率，以预测夹层的延伸范围，进而定量了泥质厚度与延伸长度之间的定量关系。中间层已建立。提出了在夹层夹杂作用下，基于曲折路径的地质模型等效放大方法。跟踪和识别每个粗网格中的单个泥质夹层，并使用地质连通性跟踪算法确定每个粗网格中的泥质夹层的平均长度，宽度和比例。计算了泥质夹层影响下曲折路径的平均流体流动长度。根据达西公式，推导了粗化网格平均渗透率的计算公式，计算出等效粗化网格的渗透率。麦凯河油砂储层的粗化结果与实际开发指标的比较表明，通过曲折路径计算得出的泥质夹层等效放大方法可以很好地反映泥质夹层的堵漏效果，更好地反映了地质条件对泥质夹层的影响。生产。
