Alternative to mathematical models of gas production: numerical experiment

[摘要] Computational experiment for comparison of quasi-one dimensional and two dimensional mathematical statements of the conjugate problem of heat exchange between gas producing well and the rocks has been carried out. The problem consists of solution of differential equations describing non-isothermal gas flow in the well and the heat conduction equation for surrounding rocks. The dependence of the coefficient of heat exchange of the gas with the hydrate layer on the time-varying flow area is taken into account in a quasi-stationary mathematical model of hydrates formation (dissociation) in gas well. The results of computational experiment correspond to two cases of production of wet and dry gas at the Otradninsky gas-condensate field.
