Abstract
Summary
In the process of oil production, the pressure in the well and reservoir can be reduced below the pressure of oil saturation with gas, in this case, oil degassing can occur both in the reservoir and the well, and only in the well. The study of mathematical models of the temperature field taking into account the Joule – Thomson effect and the adiabatic effect in the filtration of oil, water and carbonated oil in the reservoir is devoted to the work (Chekalyuk E. B., 1965; Hasan A. R. et al., 1988; Valiullin R. A. et al., 1994; Sharafutdinov R. F. et al., 2017). It is shown that the decisive contribution to the formation of a temperature anomaly at the outlet of the formation is provided by the heat of the phase transition during oil degassing. The paper discusses the features of the formation of the temperature field in the wellbore for a multi-layer system, taking into account the degassing of oil on the basis of mathematical modeling of thermohydrodynamic processes.
