储层流动单元是指影响流体流动的岩性和岩石物理性质在内部相似 ,在垂向上和横向上连续的储集带 ,它是基于油藏数值模拟的目的提出的 ,对于油气田开发 ,特别是对二次采油和三次采油具有较大的实际意义。目前国内外对流动单元的研究主要集中于探索流动单元的划分方法 ,笔者在研究各种划分方法的基础上提出了一种最简单的划分方法 ,该方法可直接从测井解释成果图上读取数据 ,求出存储系数和渗流系数 ,通过聚类分析划分出流动单元。该方法虽有不足 ,但简便易行 ,且在单一沉积微相中可取得很好的效果。
Reservoir flow unit refers to an internally similar, vertically and laterally continuous reservoir zone that affects the fluid flow in lithology and petrophysics. It is based on the objective of reservoir numerical modeling. For reservoir development, and in particular The secondary recovery and tertiary recovery have great practical significance. At present, the researches on the flow cell at home and abroad mainly focus on the exploration of the flow cell partitioning method. Based on the study of various classification methods, the author presents a simplest classification method that can be directly read from the log interpretation data Take the data, find the storage coefficient and seepage coefficient, and divide the flow unit by cluster analysis. Although this method is inadequate, it is simple and easy to implement and can achieve very good results in a single sedimentary microfacies.
