Study on influences of geological and gas source conditions on gas-chimney hydrate accumulation using a reservoir numerical simulation method
Wydane 2025-06-01“…The dynamics of this gas-chimney hydrate accumulation were analyzed, and the influences of different factors—namely, the fluid supply time, rate, and temperature—on the formation temperature and ultimate distribution of the hydrate reservoir were evaluated. The simulation results indicate that the accumulation of hydrate via gas-chimneys is significantly affected by the temperature of the gas source, the transfer state of the methane gas, and the number of cycles of alternating gas–water invasion. …”The Shenhu Area in the South China Sea is rich in oil and gas resources and has many vertical gas chimneys, making it an excellent geological environment for hydrate accumulation. This paper examines the geological conditions governing these gas-chimneys. A numerical simulation method based on the p...
