摘　　要：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3种类型,其中1类储层最好,2类储层次之,3类相对较差;最后对每个单层中3类储层的分布进行了分析,进而指导油田的进一步开发。The sedimentary environment ot Lower Kclamayi formation is alluvial fan,and rsesrvoir heterogeneity is very strong. Therefore, when the reservoir is classified, Variation coefficient, fling coefficient, and differential are added into the evaluation parameters, as to the effect of reservoir heterogeneity is full thought about. Using clustering procedure, the reservoir is divided into three types, in which the first type is the best, the second type is better and the third type is the worst. At last, the distribution of the three types in the reservoir has been studied.
