Abstract: Hydrate slurry technology, as a new way for inhibiting hydrate plug and oil-gas-water multiphase flow assurance, has drawn much attention for oil/gas production and transportation department. Therefore, this paper systematically overviews the progress on flow characteristics and rheological properties of hydrate slurry in which common experimental apparatus, morphological evolvement of hydrate slurry, the variation of flow parameters, and hydrate slurry rheology are analyzed. A couple of experiment setups are introduced, including high-pressure rheometer, high-pressure viscometer and hydrate flow loop, in which the pros and cons of hydrate loop is specially introduced. Through observation, the difference of morphological evolvement between hydrate slurry in aqueous phase and natural gas hydrate slurry in oil/gas system is presented. The variation of flow parameters during the formation of hydrate slurry, such as flow rate and pressure drop, is systematically studied. In addition, the experimental and theoretical researches on hydrate slurry rheology are also investigated in this paper. Finally, this paper proposes the existing problems, the research direction and technical route of hydrate slurry.

Key words: hydrate slurry, flow characteristics, rheological properties, morphological evolvement
