摘　　要：通过岩心流动性实验研究了文留油田水处理工艺对岩心物性的影响。结果表明:处理后水和混合水对人造岩心的渗透率无大的影响,但地层水稳定性较差,对岩心的渗透率影响较大;处理后水对岩心膨胀有一定的抑制作用,岩心膨胀体积小于3%KCl的膨胀体积,这说明处理后水不会引起地层岩心的膨胀。The effect of water treatment technology of Wenliu oil field on physical properties of the core material was studied by the experiment of core flow. The results show that the treated water and mixed water permeability of artificial core had no significant influence,but the formation water stability is poor,the influence on the core permeability is bigger; the treated water on core swelling were inhibited,the core expansion volume of less than 3% KCl,indicating that the treated water will not cause the formation of core expansion the.
