In this study, a green, simple and economical approach was used to synthesise the SiO@ZnO@Xanthan nanocomposite (NC) to modify the rheological and filtration characteristics of the water-based drilling mud. The green synthesised NCs were identified using scanning electron microscopy, energy dispersive X-ray spectroscopy, elemental mapping, X-ray diffraction and UV-Vis analytical techniques. Additionally, the effect of SiO@ZnO@Xanthan NCs on the filtration and rheological properties of mud including apparent viscosity, plastic viscosity, yield point, gel strength, mud cake and fluid loss was investigated. The obtained results confirmed that the synthesised NCs effectively improved the rheological properties of drilling mud, and considerably decreased its fluid loss and filter cake by about 54 and 92.5%, respectively. The results highly recommend the SiO@ZnO@Xanthan NC as an excellent additive to improve the rheological properties, and reduce the fluid loss and the filter cake of the drilling mud.
在这项研究中，采用了一种绿色、简单且经济的方法来合成 SiO@ZnO@黄原胶纳米复合材料（NC），以改善水基钻井泥浆的流变性和过滤特性。使用扫描电子显微镜、能谱仪、元素映射、X 射线衍射和紫外可见分析技术对绿色合成的 NC 进行了鉴定。此外，还研究了 SiO@ZnO@黄原胶 NC 对泥浆的过滤和流变性能的影响，包括表观粘度、塑性粘度、屈服值、凝胶强度、泥饼和滤失量。所得结果证实，所合成的 NC 可有效改善钻井泥浆的流变性，并可使泥浆的滤失量和滤饼分别降低约 54%和 92.5%。结果强烈推荐 SiO@ZnO@黄原胶 NC 作为一种优异的添加剂，以改善钻井泥浆的流变性，并降低其滤失量和滤饼。
