油田注水开发效果评价的灰色关联分析法

A GREY-CORRELATION ANALYSIS METHOD FOR EVALUATING WATERFLOOD ING EFFECTS DURING OILFIELD DEVELOPMENT

本文提出了一种分析评价油田注水开发效果的方法——灰色关联分析法。它不同于传统的宏观分析法,着重从微观上(或区块上)未分析注水开发效果。更确切地说,主要分析同一区块上影响采油井的主要注入井,为采取合理的增注措施提供依据。方法的要点是,使用采油井和注入井的动态数据,建立灰色关联度矩阵,由矩阵元素的大小采分析。文中对华北雁翎油田南山头几口井进行了分析,得出了与其它分析方法一致的结果,而该方法比其它任何方法都简单。

<ABSTRACT> This paper presents a grey-correlation analysis mathod for evalua- ting waterflooding effects during oilfield development. Different from the conve- ntional macroscopic analysis, it emphasizes on analyzing microscopically (or on regional blocks ) the effects of waterflooding during development.More definitely said, it mainly analyzes the major injecting wells effecting the oil producing wells in the same block, thus providing foundations for adopting resonable measures to enhance injection .The highlight of this method is establishihg a grey-correlativity matrix by using dvnamic data of oil production wells andinjection wells and analyzes the effects by values of the elements in the matrix. The results in this paper from analyzing some wells in IIuabei oilfield are consistent with that from other mehods.But this method is simpler than any others.
