The purpose of this work is to explore the effect of new anti-aggregation agent ( coconut oil amide propyl betaine ) on the flow stability of oil-water emulsion system under different water content and flow rate conditions, and confirm that the new anti-aggregation agent under high water content and even pure water conditions can still play an anti-coagulation role, so that hydrates can form stable and mobile mud. In addition, in order to explore the parameter changes in the system caused by the transient changes ( shutdown and start ) in the flow system and the flow characteristics of hydrate in the non-flat pipeline, the flow characteristics of hydrate slurry with inclined pipe section are explored, and the changes in the flow characteristics of hydrate with shutdown and restart in the actual production process are explored by stopping and restarting the equipment.
