摘要：In the hydrate risk management strategy in deep-sea oil/gas transportation pipeline, hydrates are allowed to form in the pipe line, and the petroleum products are transported in the liquid-solid slurry form. Therefore, to ensure the flow safety in deep-sea pipeline, the hydrate volume fraction and degree of agglomeration must be controlled in a safe value. The liquid-solid slurry has complex flow properties due to the introduction of the hydrate solid phase. The present work reviewed the effects of hydrate particles on the flow stability and plug mechanism in both pseudo single phase system and the gas-liquid multiphase system. The hydrate growth and deposition on pipe wall, the inter-couple of natural gas hydrate and gas-liquid multiphase flow pattern and the different plug mechanisms in different systems were discussed emphatically. Besides, an introduction of the software simulation of the hydrates slurry flow was made. Finally, based on the reviewing, this paper proposed that study on the microscopic property and quantitative description of the hydrate growth and deposition, the critical velocities of different patterns of particles distribution, and the hydrate formation and slurry flow property in different flow patterns were the main issues to be researched in the future.
