| Abstract | For the first time gas hydrate samples were recovered in the South China Sea during a drilling campaign implemented in Shenhu area in June 2007. Laboratory based studies for the characteristics of gas hydrate were carried out on two hydrate-bearing sediment samples. Observations found that gas hydrates occurred in the pores of fine grained sediments. The hydrates were structure I based on the Raman spectroscopic results. The guest gas molecules in hydrate cages were predominantly methane (> 99.3%) and trace amount of ethane (0.4%) and propane (0.04%) as determined with the method of gas chromatography. As estimated from the intensities of Raman peaks, the cage occupancy rates were more than 99% in large cage, and ~ 86% in small cage, respectively, corresponding to a hydration number of 5.9. |
