Influencing factors of subsea natural gas hydrate exploitation with CO2
Online published: 2011-12-20
This paper introduced the crystal structure of gas hydrate, discussed the feasibility on methane hydrate exploitation with CO2 from thermodynamics, and analyzed the effects of different factors on the replacement reaction, including loricae effect, temperature, pressure, crystal structure, crystal cage fill fraction, porous media, salinity, additive and microemulsion. It is pointed out that reinforcement of the reaction procedure by multi measures is the research emphasis in the future, and the research provides a newthought for CO2 subsea preservation and natural gas hydrate expoitation.
Key words: log curve; formation component analysis; porosity
