Most hydrate-bearing sediments worldwide exhibit mixed pore- and fracture-filling hydrates. Due to the high exploitation value, pore-filling hydrate production is focus of current research, there a lack systematic research on decomposition hydrates their effects evolution temperature pressure in sediments. If only characteristics are studied while its process ignored, obtained results would be inconsistent with actual situation. Therefore, this study, different dipping angles were studied,...
Summary So far, a total of 11 hydrate trial production projects have been carried out all over the world, which used single vertical well or horizontal to carry by depressurization method combined with other methods. These traditional methods some limitations: The has small contact area reservoir, and transmission range temperature pressure is limited; therefore, productivity low. can improve from magnitude order; however, there long distance standard commercial marine hydrate. Therefore, it...
Abstract Natural gas hydrate (NGH) is an important future resource for the 21 st century and a strategic with potential commercial development in third energy transition. It of great significance to accurately predict productivity hydrate‐bearing sediments (HBS). The multi‐phase seepage parameters HBS include permeability, porosity, which closely related saturation, has direct impact on content. Existing research shown that these have productivity. Permeability directly affects transmission...
Summary Due to a dipping and folded structure, hydrate-bearing sediments (HBS) have obvious fluctuation characteristics, the internal temperature pressure of HBS are unevenly distributed. Subsequently, gas water production natural hydrate (NGH) is affected. When using numerical simulation method predict effectively productivity HBS, it necessary establish conceptual model that considers formation fluctuation. However, few reported studies accurately describe characteristics in models....
Natural gas hydrate (NGH) has the advantages of wide distribution and large reserves, attracted extensive attention from international community. Researchers have conducted quantitative microscopic pore-scale simulations, exploitation surveys, laboratory tests, numerical but commercial development is still a long way off. In view existing problem insufficient productivity, enlarged permeable well wall technology studied in this paper, which method to improve reservoir productivity by...
