摘要
探讨了绥中36-1油田回注污水在不同悬浮物粒径、不同悬浮物浓度以及不同注入体积时对岩心渗透率的影响,实验结果表明:悬浮微粒直径越大、浓度越大,伤害率越高;地层的渗透率越低,损害越大;随着注入水体积的增大,岩心渗透率呈明显下降的趋势;注入水对地层的损害程度为D11>清污混注>水源井。
Effect of the reinjection of Suizhong 36-1 oilfield produced water with different suspended particle diameter, different suspended matter concentration and different injection volume on the core permeability was investigated. The experimental results show that： the larger the suspended particles diameter and the higher the concentration, the higher the damage rate; and the lower the permeability of the stratum, the higher the damage. With the increase of water injection volume, the core permeability obviously decreases; The damage degree of the injected water to the formation ： D11 mixed injection water wells.
