Abstract： In order to solve the problem caused by the deterioration of drilling fluid performance under extreme drilling conditions， the use of nanomaterials to improve the performance of drilling fluid has always been an important direction of research. In this paper， the effects of water-based drilling fluids with different nanomaterials on shale stability， filtration loss control， mud cake status， borehole reinforcement， lubrication and other performance effects of drilling operations are summarized. The results of the studies show that the use of nanomaterials can effectively improve the performance of water-based drilling fluids.

Keywords： nanomaterials;water-based drilling fluids;filtration loss reduction
