| Abstract: |
| The experimental apparatus for gas hydrate in porous sediments is introduced.Under different constant temperature(1.0℃,2.0℃,4.0℃,7.0℃,10.℃),the formation and dissociation of methane hydrate with three kinde of sediments granule(average diameters 0.15mm,0.06mm,0.03mm respectively) are studied. The saturation of methane hydrate in porous sediments is got by measuring the consumption of methane in vesssel. The results find that the saturation increases as formation pressure and porosity of sediments increase. It is also showed that the P-T curve in distilled water,which is accordant with the results from other papets sediments departure to left comparing to the P-T curve in distilled water, which is accordant with the results from other papers involved . |
