| 摘 要： | 注水水质是影响开发指标的重要因素。在注水开发中,注入水水质的好坏不仅影响注水工艺系统的效率,还影响油藏的开发指标及开发效果。通过实验研究和经验公式计算进行了注水水质影响下的油藏开发指标（含水率、波及系数、吸水指数及采收率）的变化规律研究;并做出了相应的变化规律曲线,分析了水质对这些开发指标的影响。注水水质差会导致油相相对渗透率急剧下降,含水率增长迅速,波及系数减小,吸水指数下降,采收率也降低。研究结果为注水水质标准的制定提供了一定的理论依据。

| Abstract: | The water quality is an important factor for the development index.In water flooding,the quality of injected water not only has influence on the efficiency of the process system,but also on the index and result of oilfield development.This article studies the variety rule of the reservoir development index,(water content,conformance factor,adsorption index and recovery efficiency) influenced by different injected water through experiments and some empirical formulae.Poor water quality leads to a sharp decli... |

| Keywords: | development index water content ratio conformance factor adsorption index recovery efficiency injected water quality. |
