非均质综合指数法划分储层流动单元

IDENTIFYING THE FLOW UNITS WITH RESERVOIR HETEROGENEITY INDICATOR

近年来,流动单元概念已被广泛用于储层研究中,取得了较好的效果.但怎样充分利用反映流储层及流动非均质性的各个参数来划分流动单元,目前没有统一的认识,文献中多局限在传统的划分方法上.基于充分利用各个反映储层特性的参数的思想,笔者提出了非均质综合指数法划分储层流动单元,并用这种方法研究了新疆油田某井区储层流动单元.由实践验证,这是一种比较行之有效的方法,划分的结果是可靠的.

In recent years, the conception of flow unit has been widely used in researches of oil reservoirs successfully. However, there isn't a commom knowledge about how to make full use of the variety of parameters associated with the characteristics of oil reservoir. Most of the published papers on division of flow units used only the conventional methods. In order of making full of use of all the available parameters, we suggested a new method of Reservoir Heterogeneity Indicator for divisions of flow units, and applied it in the research of Xinjing Oilfield. Our research confirmed that the method is suitable in this Oilfield and the results are reliable.
