| 摘 要： | 围绕废弃钻井液的处理,采用非分散红外TOC仪测聚合物吸附量,研究了聚合物PAM、PHP、FA367、CPAM在粘土及钻井液固体颗粒表面的吸附特性,研究结果表明聚合物在粘土颗粒表面的吸附是高度不可逆的,聚合物高分子与粘土因氢键、静电及嵌入三种相互作用方式而吸附,阳离子型聚合物絮凝剂在钻井液固体颗粒表面比阴离子和非离子型絮凝剂有高得多的吸附性能,废弃钻井液的絮凝主要以“吸附架桥”机理为主。

| Abstract: | Around the treatment of the waste drilling fluid, determining the polymer adsorbance uses non\|dispersal infrared light TOC meter, Studying adsorption characteristics of the polymers of PAM、PHP、FA367 and CPAM which are adsorbed on the surface of the clay and the solids in the drilling fluid The results show that the high polymer adsorption on the surface of the clay solids in ways of hydrogen bond, static electricity and embedment is highly reversible, the cationic polymer flocculant adsorption characteristic on the surface of the drilling fluid solids is more high than those of the anionic and non\|ionic ones, the waste drilling fluid flocculant majors in“adsorption bridging”mechanism |
