摘要： 在油藏注水开发后期,查清剩余油分布、合理部署注采井网、制定出开发调整措施是油藏开发管理的重要工作。为此,首先要了解井间连通性,弄清注水井水流方向。应用Spearman秩相关系数分析方法,借助石南油田石南4井区三工河组油藏的油井与注水井的生产动态数据,从动态的角度对井间连通性和注入水流动方向进行了研究。该方法实现起来比较简单、省时,适合于油田现场的实际情况。

Abstract: In the late stage of waterflooding, the key efforts of reservoir operation or management focus on the understanding of remained oil distribution, the rational arrangement of producer-injector spacing and the measures making for development modification, of which to grasp the interwell communication and the injected water flow direction is the chief task. Spearman's order correlation coefficient is applied to study of them by taking the production performance data from producers and injectors in Sangonghe reservoir of Shinan-4 Wellblock in Shinan oilfield as analytical parameters. The case study indicates that this method is simple, save-time and suitable for field application.

Key words: water flooding, flow direction, order, correlation coefficient
