摘要
储层非均质的影响因素多,非均质对油藏的注水开发效果控制作用强,特别是在开发后期影响剩余油的分布。在对影响储层非均质的因素综合分析的基础上,提出了利用灰色系统中的灰色聚类理论来确定储层非均质分布。该方法能够对影响储层非均质的多种因素进行综合考虑、综合分析、综合分类,在梁家楼油田南区C47块S3中油层非均质研究中取得了较好的应用,划分出了特强非均质区、强非均质区、中等非均质区、弱非均质区、特弱非均质区,为储层非均质的研究和剩余油挖潜提供了新的方法。
There are many factors that affect the heterogeneity of a reservoir. The control of the heterogeneity of a reservoir over the water injection development is very strong, especially over the distribution of the residual oil in the high water cutting development phase. On the basis of the comprehensive analysis of the factors that affect the heterogeneity of a reservoir, the paper puts up the theory of using the clustering-theory in Grey System to determine the distribution of the heterogeneity. This method can conduct the comprehensive thoughts, analysis and sorting on many kinds of factors that affect the heterogeneity of a reservoir. It has been applied to the Liangjialou oil- field C47 block S3 reservoirs and gained good results. It locates the extra powerful heterogeneity area, powerful heterogeneity area, moderate heterogeneity area, weak heterogeneity area, and extra-weak heterogeneity area. This paper puts forward a new method for the study of the heterogeneity of a reservoir and the excavation of the residual oil.
