模糊聚类分析在储层流动单元研究中的应用

Application of fuzzy clustering analysis to study on reservoir flow unit

储层流动单元研究是一种研究储层内部流体渗流差异的技术方法,在油田开发中后期的精细油藏描述中具有重要的实际意义。以准格尔盆地某油藏为例,基于模糊数学原理,提出采用模糊聚类分析法研究划分储层流动单元。应用该方法首先进行数据标准化,建立相似关系矩阵;再确定模糊等价关系,采用模糊等价法进行模糊聚类分析;最终绘出不同置信水平入的动态聚类谱系图,划分出四类流动单元,分析流动单元分类指标与流动带划分的相关性,给出划分标准。计算分析结果准确,可为用于指导开发方案调整与挖潜。

Reservoir flow unit is a research study of fluid flow difference between the internal reservoir of technical methods, in the oil field development in the latter part of the detailed reservoir description has important practical significance. In this paper, a reservoir zhungeer basin as an example, based on fuzzy mathematics theory, the use of fuzzy clustering analysis research division of reservoir flow units. First of all, the application of the method for data standardization, the establishment of a similar relationship between the matrix and then determine the fuzzy equivalence relation, fuzzy equivalence of fuzzy clustering analysis method, the final mapping of the different confidence level h dynamic clustering pedigree chart, divided into four categories of mobile unit analysis of flow units and flow classification with delineation of indicators of relevance, given the criteria for the classification. Accurate calculation of the results of the analysis can be used to guide the development of programs for adjustment and potential.
