Marine natural gas hydrate (MNGH) accounts for 99% of the global hydrate resources, 90% of which are deposited in marine clayey silt sediments. MNGH has great economic benefits; however, the large-scale commercial exploitation of hydrates is severely restricted by technology. High-pressure-and low-temperature water jet method is a new kind of MNGH solid exploitation method. This article represents analysis of its characteristics and determination of the critical velocity by laboratory experiment. Results show that the new method is feasible for MNGH exploitation, and the present study can provide reference for subsequent MNGH exploitation research and engineering applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
