Polymer drag reducers can reduce the energy loss of pipeline transportation effectively, but are easy to degrade. The factors influencing the drag reduction efficiency and the mechanism of the drag reduction were discussed. Several methods for improving the polymer drag reducer performances and storage stability were summarized, including grafting, changing the molecular structure, adding surfactants, introducing associative bond and so on, in which, adding surfactants could improve the performances of the polymer drag reducers in a wider range of the Reynolds number, and provide the better anti-degradation capacity and the longer drag-reduction period. The prospects of the polymer drag reducers were proposed in the end.
