通过接触角测试、扫描电镜微观结构观察以及X RD分析表面污垢,在模拟三元复合驱液与地层水的混合液中,研究了设备表面的不同处理方式对其抗结垢性能的影响。结果表明,固体表面污垢的形成与水溶液在表面润湿难易程度密切相关。亲水表面污垢颗粒容易吸附,利于结晶垢的生长;疏水表面污垢颗粒与之接触困难,污垢颗粒在表面的吸附和晶体长大过程都很难进行,但不同的表面对污垢的晶型影响不大。不同表面处理后的表面微细结构变化对表面的润湿性影响较大;采用降低设备表面水润湿性的表面处理方式将提高设备表面的抗结垢能力。
通過接觸角測試、掃描電鏡微觀結構觀察以及X RD分析錶麵汙垢,在模擬三元複閤驅液與地層水的混閤液中,研究瞭設備錶麵的不同處理方式對其抗結垢性能的影響。結果錶明,固體錶麵汙垢的形成與水溶液在錶麵潤濕難易程度密切相關。親水錶麵汙垢顆粒容易吸附,利于結晶垢的生長;疏水錶麵汙垢顆粒與之接觸睏難,汙垢顆粒在錶麵的吸附和晶體長大過程都很難進行,但不同的錶麵對汙垢的晶型影響不大。不同錶麵處理後的錶麵微細結構變化對錶麵的潤濕性影響較大;採用降低設備錶麵水潤濕性的錶麵處理方式將提高設備錶麵的抗結垢能力。

By testing contact angles on surface ,observing surface microstructures with scan‐ning electron microscopy and analyzing surface dirt with XRD ,the influences of fouling resistance with different treatment of equipment surface were studied in the mixed liquid of simulation ASP flooding fluid with formation water .The results showed that the formation of dirt on solid sur‐face was closely related to the degree of water wetting the surface .Hydrophilic surface easily ab‐sorbed the dirt particles ,and was conductive to the growth of crystallization fouling ;and hydro‐phobic surface contacted with dirt particles difficultly ,the adsorption of dirt particles and the growth process of crystal were difficult ,but the effect of different surface on dirt polymorphs was little .The changes of surface micro‐structural after different surface treatments largely impacted on the surface wettability .By reducing the water wettability of equipment surface would enhance the anti‐fouling ability of equipment surface .
