吴起采油厂水源水与储层配伍性能研究

The study of compatibility of source water and reservoir properties in Wuqi oil production plant

本文通过对吴起采油厂的水源水与长2、长6、延9等地层水的配伍性实验,结果表明,水源水与延9、长6储层的地层水配伍性好,而与长6储层地层水配伍性较差。水源水与储层配伍性能实验结果表明,水源水在延9和长2储层K2/K1均在大于0.95范围内,说明水源水与储层是配伍的,对储层不会造成伤害。而水源水在长6储层K2/K1小于0.95,说明水源水对储层造成一定的伤害。

In the article,Based on the experiments of compatibility source water and the formation water of Chang 2,Chang 6,Chang 9 in Wuqi oil plant,the results show that the source water and the extension of Chang 9,Chang 6 reservoir formation water compatibility is good,with a Chang 6 reservoir formation water compatibility is poor.Compatibility of water and reservoir water test results show that the extension of source water in the reservoir Chang 9 and Chang 2 K2/K1 are in the range of greater than 0.95,indicating that water is the compatibility of water and reservoir,the reservoir will not cause harm.The source water reservoir in the Chang 6 K2/K1 is less than 0.95,indicating the source water caused some damage to the reservoir.
