Abstrakt:	According to the characteristics of marine natural gas hydrate, China has proposed the solid-state fluidization exploitation technology or natural gas hydrate, with subsea exploitation being key to the commercial recovery of gas. In this paper, two new integrated tools are proposed for breaking and collecting natural gas hydrate, and their working principles and steps are illustrated. Finite element analysis, three-dimensional modeling, and simulations were conducted for both exploitation tools to verify their technological feasibility. The results show that the two exploitation tools can effectively improve the efficiency of hydrate exploitation and ensure the stability of the hydrate reservoir. This provides a reference for further research on the solid-state fluidization exploitation technology of marine gas hydrates. [ABSTRACT FROM AUTHOR]
