表面润湿性对三元复合驱设备结垢的影响
Influence of surface wettability on devices scaling in ASP flooding
摘要
Abstract
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 .关键词
