纳米材料在钻井液封堵降滤失中的研究进展

Research Progress of Nanomaterials in Drilling Fluid Plugging and Fluid Loss Reduction

纳米技术及纳米材料的发展已渗透至医药、国防军工、涂料、芯片等诸多领域,得到广泛且实际可行的应用。因其具备纳米级尺寸且比表面积大,与钻井液在封堵降滤失方面需求高度匹配,也逐渐成为该领域研究人员关注的焦点。本文简要阐述了包括无机、有机以及两者复合在内的多类型纳米材料在钻井液封堵降滤失中的作用效果及作用机理,以期对未来钻井液封堵降滤失用纳米材料的研发方向和推广应用提供参考。

The development of nanotechnology and nanomaterials has penetrated into many fields such as medicine, defense and military industry, coatings,chips, etc., and has been widely and practically applied. Because of its nano-scale size and high specific surface area, it is highly matched with the needs of drilling fluids in plugging and filtration reduction, and has gradually become the focus of researchers in this field. This paper briefly expounds the effect and mechanism of multi-type nanomaterials including inorganic, organic and composite materials in drilling fluid plugging and filtration reduction, in order to provide a reference for the research and development direction and popularization and application of nanomaterials for drilling fluid plugging and fluid loss reduction in the future.
