Simulation of Hydrate Formation During Natural Gas Production

Reporter: Rozhin I.

In the frame work of tube hydraulics quasi-stationary model of natural gas hydrates formation (dissociation) in gas wells has been proposed. The corresponding algorithm of its realization is based on the forth order Runge - Kutta method and on the iteration procedure which unites the problem of calculation of pressure and temperature during gas flow in well with changing cross-section with the problem of hydrate layer dynamics(modification of the classical Stefan Problem for the case where phase transition temperature depends on gas flow pressure). Some results of calculations are given where one can see the influence of model parameters and initial conditions on dynamics of hydrate plug formation. These calculations are based on real cases related to gas fields of Eastern Siberia.
