Abstract
The paper considers the heating of an oil well by a heating cable in periodic mode. A mathematical model of heat and mass transfer processes in an axisymmetric formulation was proposed. The proposed model was implemented numerically using the finite element method in the ANSYS Fluent. The implementation of the model made it possible to obtain a temperature field along the entire depth of the well, evaluate the effect of the heating cable and give recommendations on the periodic heating regime for specific technological production conditions. The proposed mathematical model is suitable for all fields with a vertical production method. The obtained results will be useful for the oil and gas industry in the fight against asphalt-resin-paraffin deposits and hydrates. The implementation of the mathematical model makes it possible to estimate the required power and operating time of the heating cable. This approach makes it possible to effectively and economically solve the problem of wax deposition.
