| 摘 要： | 注水开发油田进入高含水期,由于储层非均质性和长期注水开发,将造成合采油井层间矛盾突出。因合采层位组合大多基于层系划分原则,缺乏对合采层位组合方法系统、定量的研究。通过油田动、静态资料分析,深入研究油井层间组合的影响因素以及不同层间组合对产液的影响,确定层位组合的合理技术界限,并由此提出对应注水井的分级配注要求。现场实施效果表明,该方法具有增加产油量、减缓层间干扰、提高低渗透层动用程度等优点。

| Abstract: | Multilayer producers tend to have interlayer problems due to reservoir heterogeneity after long time of water flooding. The combinations of commingled production horizons are determined based on reservoir series division with little systemic and quantitative study. The rational technical limits of the combination of commingled production horizons are defined through analysis of dynamic and static oilfield data and deep study of the influencing factors of interlayer combination as well as the effect of diffe... |
