十六烷基三甲基溴化铵在不同油层矿物颗粒上吸附的光谱学表征

Spectroscopic Characterization of the Absorption of CTAB on the Particles of Different Reservoir Minerals

利用 FT- IR和 XRD两种光谱学方法 ,对阳离子表面活剂十六烷基三甲基溴化铵( CTAB)在高岭土、石英砂和蒙脱土颗粒上的吸附进行了光谱学表征 .实验结果表明 ,光谱分析能够直观地反映矿物颗粒对活性剂的吸附。

Spectroscopic characterization of the absorption of cationic surfactant CTAB on the particles of Kaolinite ,Quartz and Montmorillonite has been carried out by means of XRD and FT IR methods.The experimental results showed that the absorption of surfactant CTAB,the relative quantities of absorption on different mineral particles and the change of mineral structure after absorption had been directly reflected by spectroscopic analysis.
