Thermal recovery method of submarine gas hydrate based on a thermoelectric generator

摘要

1.Objective Natural gas hydrates are considered as a potential alternative fuel resource to petroleum and gas (Chong ZR et al.,2016),which can be exploited by means of depressurization,thermal method,inhibitor injection,etc.For the thermal method,gas hydrates are decomposed into water and methane when the reservoir is heated to above the equilibrium temperature of gas hydrate (Li X et al.,2016). However,the thermal recovery method needs a great deal of heat,and thus the feasibility of economic exploitation is reduced.
