Multi–front phase transitions during nonisothermal filtration of live paraffin–base crude
R. F. Sharafutdinov Bashkir State University, Ufa, 450000
Abstract:
By numerical modeling of nonisothermal filtration of multicomponent oil with allowance for the Joule–Thomson effect, adiabatic effect, and heat of phase transitions that occur during oil degassing and paraffin crystallization, the formation of profiles of phase–saturation, concentrations of oil components, and temperature in oil beds is studied. It is shown that consideration of many components results in occurrence of phase–transition fronts during degassing of oil components and paraffin crystallization. In turn, paraffin crystallization gives rise to temperature oscillations. Depending on the initial paraffin concentration and on the ratio of phase–transition heats for oil degassing and paraffin crystallization in an oil bed, either decaying or steady–state temperature oscillations are observed.
