| 摘要: |
| 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。 |

| Abstract: |
| A flow unit is defined as a volume of reservoir rocks that is extensive both vertically and laterally,and has similar lithology and physical property that affect fluid flows.The flow units are based on the numerical modelling of petroleum deposits,and has important implications for the development of oil and gas fields,especially for the secondary or tertiary recovery.The current research focus both at home and abroad is directed more to the classification schemes of flow units.This paper aims to provide a useful tool by which the storage coefficients and seepage coefficients can be calculated in terms of the data on porosity and permeability.As a result,the flow units can be identified by means of cluster analysis of the storage coefficients and seepage coefficients obtained.This method is convinent and conductive to the analysis of a single sedimentary microfacies. |
