The effect of multi-walled carbon nanotubes (MWCNTs) decorated with ZnONPs on the rheological and filtration properties of conventional water-based drilling muds (WBDM) was investigated. ZnONPs and MWCNTs were synthesized separately, then MWCNTs were decorated with ZnONPs by chemical vapor deposition method and characterized by scanning electron microscopy and X-ray photoelectron spectroscopy. Synthesized and characterized ZnONPs/MWCNTs were added to conventional WBDM at a rate of 0.001% to 0.01%, and then rheological and filtration loss analyses were performed according to American Petroleum Institute standards. With the addition of ZnONPs/MWCNTs to the conventional WBDM, the values of plastic viscosity, apparent viscosity, yield point, cake thickness, 10 s and 10 min values increased by 42.8%, 31.6%, 28%, 22%, 25%, and 38.9%, respectively, while the value of filtration loss decreased by 13.8%. When all results were examined, the best addition rate was 0.01%. The results obtained show that ZnONPs/MWCNTs improved the rheological and the filtration loss properties of the drilling mud, proving that ZnONPs/MWCNTs can be used as additives in conventional WBDM.

研究了用 ZnONPs 装饰的多壁碳纳米管 (MWCNTs) 对常规水基钻井泥浆 (WBDM) 流变学和过滤性能的影响。分别合成了ZnONPs和MWCNTs，然后通过化学气相沉积法用ZnONPs装饰MWCNTs，并通过扫描电子显微镜和X射线光电子能谱对其进行表征。将合成和表征的 ZnONPs/MWCNTs 以 0.001% 至 0.01% 的比例添加到常规 WBDM 中，然后根据美国石油协会的标准进行流变和过滤损失分析。在常规WBDM中加入ZnONPs/MWCNTs后，塑性粘度、表观粘度、屈服点、滤饼厚度、10 s和10 min值分别增加了42.8%、31.6%、28%、22%、25%，和 38.9%，分别为 而过滤损失值下降了13.8%。当检查所有结果时，最佳添加率为0.01%。所得结果表明，ZnONPs/MWCNTs 改善了钻井泥浆的流变性能和滤失性能，证明 ZnONPs/MWCNTs 可用作常规 WBDM 的添加剂。
