| 摘 要： | 通过不同水样的岩心驱替实验，研究了注入水质对岩心渗透率的伤害率。结果表明：①现场注入水对岩心渗透率的伤害率大于50％；②注入处理不彻底的水后岩心渗透率的伤害变小，但伤害深度变大；③薄膜过滤后的水和处理后的水对岩心的伤害率基本相同；④注入水质应按处理后的水质指标控制。

| Abstract: | The damage to core permeability due to injection water quality is studied by means of core driving experiment with different water.The results shows that the damage is more than 50% for the in situ injection.The damage becomes less but the degree is greater when the injection water is not treated thoroughly.While the damage done by the treated water seems similar to that done by the filtered water.It is concluded that the injection water quality should be controled by the index of the treated water. |
