The Experimental Studies and Development Concept for the Offshore Natural Gas Hydrate

摘要

Based on the brief review of the progresses on the natural gas hydrate exploration ， this paper presents a concept development method for offshore natural gas hydrate ， considering the current deepwater engineering practice. A set of one dimension experimental facility has been built to simulate the natural gas hydrate development process. The experimental studied of the depressurization and heat injection method used for produce natural gases from hydrates have been carried out. The hydrate dissociation kinetics, gas and water production rate have been analyzed, which are meaningful for the pilot scale and real industry scale production of natural gas hydrate.
