摘要
在注水开发油藏开发后期 ,了解井间连通性 ,弄清注入水流动方向 ,从而摸清剩余油分布 ,是开发调整的重要步骤和内容。本文以辽河油田茨 78断块 S32段为例 ,借助油井与注水井的生产动态数据 ,应用灰色关联度分析方法 ,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 ,弥补了在油藏动态描述中过分依赖小层对比和数值模拟的不足 ,其结果同生产实际一致。
At late stage of waterflooding production, it i s important to understand the communication among wells, to ascertain the waterflo oding directions and to clarify the distribution of remained oil. In this paper, the dynamic production data from S 3 2 segment of Ci-78 fault block in liaoh e oil field were used to study the inter-well communication and weterflooding d irection by means of Grey Association-ratio Analysis. The result of this study has been proved to be practical and successful in contrast to the previous work of dynamic description of reservoir, which mainly depended on the numerical simu lation and sublayer correlation.
