摘　　要：在高含水期油藏注水开发过程中,采用分层配注方法对获得油藏剩余油分布规律,各层段合理配注量,提高油田开发水平和管理水平具有重要意义.首先以油田或区块为研究对象,从物质平衡方程的定义出发,推导出注采比、压力梯度和含水率的关系式,通过下年度规划的含水率指标确定该油田或区块的注采比;且围绕着如何获得符合油田实际的通用的劈分系数进行分析与研究,从而得到单井配注量和分注井层段配注量及各层段性质.通过对分层配注结果的分析和评价,得到油藏总体配注误差较小,油藏含水率降低,采出程度提高的效果.结果表明分层配注方法科学合理,简单实用,对于高含水期油田具有很好的推广应用价值.The methods of separate stratum injection allocation are significance for re- maining oil distribution, injection allocation of interval and the level of exploitation and administration in high water cut stage. First, we should derive IWR, gradient of pressure arid water cut. The injection allocation of single well and injection wells are determined by the research of Split coefficient.we also get the result of small error, lower water cut, high degree of reservoir recovery by anaysising the result of separate stratum injection allocation. The result shows that separate stratum injection allocation is Scientific and reasonable, sim- ple and application value for the oil field in high water cut stage.
