Feasibility of wettability measured by n-heptanol method is proved, which not only adapts to quantitative oil-wetted percentage measurement for quartz sands or other grains, but also for the cores. 验证了正庚醇法测定润湿性的可行性,正庚醇方法既适合于石英砂或其它岩石颗粒上亲油百分数的定量测定,也用于岩心中孔隙表面亲油百分数的定量测定。
The esterified white carbon has been prepared by the reaction between the surface hydroxyl groups of white carbon and n-heptanol or n-octanol. 本文利用正庚醇或正辛醇与白炭黑表面羟基反应制备了酯化白炭黑。
