“…Mathematical modeling methods are widely used [3] for the 'well -formation' system, model problems are solved as stationary [4] and non-stationary [5] problems. Asymptotic methods for determining a temperature field are developed taking into account the hydrodynamic regime of the fluid flow in a well [6,7]. However, in most cases, when problems are set and solved, empirical relations for calculating a heat transfer coefficient are used as closing dependencies in the system of energy equations [8].…”

The mathematical model of conjugate heat exchange is proposed for the turbulent movement of reservoir oil in a vertical well section. The motion of the medium is described using a two-dimensional axisymmetric stationary formulation and boundary layer equations. The movement of the turbulent flow of reservoir oil due to reservoir energy is presented. The liquid medium is a mixture of reservoir oil with dissolved gas and formation water. The results of the numerical modeling are presented in the form of dependences of the changing flow rate, temperature, and mass fraction of paraffin deposits that occur along the full vertical extent of the well. The results obtained describe the thermobaric state of the well under the condition of conjugate heat exchange between the fluid flow and the production pipe.
