Thus,the granule component of the sediment is changing with the proportion of fine and course sediments along the river flow,and the uniformity of these particles is different at different place.
通过水槽试验研究了不同泥沙浓度及水流条件对泥沙颗粒均匀性沿垂向分布规律的影响,试验表明,在泥沙浓度或者水流条件较小的情况下,非均匀系数沿垂向分布是逐渐增大的,即越接近床面,颗粒越均匀,非均匀系数越接近1。

白碱滩油田六中区克下组为冲积扇沉积,储集层非均质性严重,在对这类储层进行综合评价时,除了用到孔隙度、渗透率和泥质含量等常规评价参数外,在这里增加了变异系数、突进系数和级差三个参数,使得非均质性的作用在储层综合分类评价中得到充分体现;然后应用聚类分析将储集层分为三种类型,其中Ⅰ类储层最好,Ⅱ类储层次之,Ⅲ类相对较差;最后对每个单层中三类储层的分布进行了分析,进而指导油田的进一步开发。
