摘要
注水开发是保证水驱油田高产、稳产的最重要措施之一。在注水时机、注水方式一定的情况下,注水强度,尤其是各注水井的注水量配置显得非常重要。合理的单井配注量,可以有效缓解平面矛盾、层间矛盾、层内矛盾和提高水驱油田开发效果、水驱采收率。在对目前存在的配注方法的综合分析和研究之后,提出以水驱油田注水井井组为研究单元,采用多元回归方法来确定注水井井组配注量,并基于多元回归方法的回归系数和偏相关系数,分别建立了多元回归模型Ⅰ、Ⅱ。实例分析表明,本方法简单、实用性强。
Waterflood development is one of crucial measures for high and stable productions. With definite water injection timing and pattern, water injection intensity and, especially, the injection allocation rate is very important. The proper injection allocation rate of well can effectively relieve the contradictions of plane, interlayer and inherent layers, and improve the effects of oilfield exploitation by waterflood or water drive process. After synthetically analyses and researches of the existing methods for injection allocation rate, this article takes the group of water-injecting wells in waterflood oilfield as the research unit, the multiple regression method to decide the injection allocation rate is applied, by which and its regression coefficient and partial correlation coefficient, the multivariate regression models of ModelⅠ and Model Ⅱ are developed. The case study indicates that this method is characterized by simpleness and practicability for application.
