【摘要】 纤维素作为常用钻井液添加剂被广泛应用于多种水基钻井液体系中，可以有效降低钻井液失水、增强携带岩屑性能、改善钻井液流变性；纳米纤维素作为新型钻井液添加剂既具有常规纤维素的优点，又具有抗温、抗盐碱等性能，可以显著改善钻井液的稳定性能和流变性能，有效降低钻井液的滤失量。介绍了目前制备纳米纤维素的方法以及纳米纤维素在钻井液中的应用，并对纳米纤维素在钻井液中的应用作了展望，旨为制备新型抗高温环保型钻井液处理剂提供参考。更多还原

【Abstract】 Celluloses are a common additive used in various water-based drilling fluids to effectively reduce the filtration rate,enhance the drilled solids suspending capacity and improve the rheology of the drilling fluids. Nanocellulose as an innovative drilling fluid additive has, apart from the advantages of the common cellulose, new properties such as high temperature stability and resistance to salt and alkali contamination. The nanocellulose also remarkably improve the stability and rheology, and effectively reduce the filtration rate of the drilling fluids. This paper introduces the methods presently used to produce nanocellulose and the application of nanocellulose in drilling fluids. Prospects are made in the paper of the application of the nanocellulose in drilling fluids, aiming at providing a reference for producing new environmentally-friendly high temperature drilling fluid additives.更多还原
