Numerical investigation of the decomposition of gas hydrates coexisting with gas in natural reservoirs

摘要: The problem of methane hydrate decomposition in a reservoir saturated with gas and mixture is investigated numerically. results the numerical simulation an analytic solution obtained linear approximation are compared. It shown that for high-permeability rocks convective heat transfer near-well space predominates over conductive transfer. This makes use intra-well heaters ineffective. found increase well pressures decrease permeability suppress formation extended dissociation region. Critical diagrams existence frontal regime constructed.
