Some Problems of Modeling the Impact on Gas Hydrates on the Basis of Splitting by Physical Processes

摘要

In this work we consider an equilibrium joint model of a two-component three-phase (water, gas, hydrate) filtration fluid dynamics and two-phase processes in the thawed zone with no gas hydrates, for which splitting by physical processes is performed. Algorithms for the joint calculation of hydrate-containing and thawed states of a fluid-dynamic medium are described. Examples of calculations of technogenic depressive effects near the wells on the dynamics of spatial distributions of gas hydrates' thawing and the formation of thawed two-phase zones are given.
