In order to ensure the safe and reliable production of the subsea natural gas hydrate, it is necessary to study its flow assurance due to the complicated deep water environment. In this paper, the production patterns of subsea natural gas hydrate and the flow assurance problems in its production process are summarized. It also discusses on the development of the prediction model, which contains hydrates regeneration, hydrate particles migration and slug flow. At the same time, the development direction of the research on the flow assurance of the natural gas hydrate is also put forward. The article will provide a reference for the design of flow assurance of subsea natural gas hydrate.
