Natural gas hydrate is a kind of non-stoichiometric cage complex formed by the interaction of host and guest molecules.Natural gas hydrate will play an important role in natural gas transportation,peak shaving,and storage processes,and the key to the application of natural gas hydrate technology is to deeply grasp the formation and ablation of natural gas hydrate.Therefore,this paper reveals the decomposition law of natural gas hydrate under the pipeline flow system by studying the relationship between hydrate ablation and time under the five influencing factors of chemical agent type,dosage,depressurization rate,depressurization pressure difference and depressurization time as well as the distribution law along the pipeline.
