Slickwater hydraulic fracturing is widely used to improve the efficiency of shale gas exploitation in North America and it also has a broad application prospect in China. The friction reducers are water-soluble polymeric additives which are added to slickwater to reduce friction loss during pumping. In this paper,the mechanism of water-soluble polymeric drag reduction was summed up,and recent progresses in the research of friction reducers,including polysaccharides friction reducers,poly(ethylene oxide) friction reducers and polyacrylamide friction reducer,used in the completion of shale gas were reviewed. The environmentally friendly friction reducers with high drag reduce ability,low damage to shale reservoir and low cost would be the development direction in future.
