| 摘 要： | 通过分析存水率与采出程度、压力、采液指数的关系,探讨油田开发后期提高存水率的途径,得出了提高油田或区块的存水率,需针对油田不同开发时期的开采特点、油层物性,认真分析区分对待,采取增注、整体调剖、封堵高含水层、关停高含水低效井等措施,提高单元压力保持水平,改善油田开发效果。

| Abstract: | This paper discusses measures to improve retaining rate of injected water in reservoir in late stage of oilfield development through analyzing the relationships between retaining rate of injected water and the ratio of total oil produced to OOIP, pressure, and fluid productivity index. In order to improve retaining rate of injected water in an oilfield or a block, appropriate measures should be selected according to the characteristics of production in different development stages and poroperm characteristics of oil layers. These measures include enhancement water injection, overall correction of profile, plugging layers with high water saturation and shutting down stripper wells with high water cut. They can be used to maintain reservoir pressure in a development unit and to improve development effects of oilfields. |
