- Natural gas hydrate, inhibitor, composite inhibitor, preventing hydrate formation
In recent years, the research about natural gas hydrate inhibitors has transformed from thermodynamics inhibitors to kinetic inhibitors and anti-agglomerant inhibitors in the deepwater drilling. However, once the malfunction occurred in the injection system, kinetic inhibitors is powerless facing the hydrate plug resulted from irregular shut-in gas wells or lack of inhibitors. Meanwhile, surfactants would not be economically viable as a single inhibitor. Considering the single inhibitors have some limitations in the practical application, kinetic inhibitors, anti-agglomerant inhibitors, thermodynamic inhibitors and other auxiliary agent are used in combination to prevent hydrate plug. This article is a comprehensive study of the advantages and disadvantages of various inhibitors, which develops a complex scheme, reduces the amount of compsite inhibitors, increasing the supercooling degree, and will be more suitable for industrial application.
