One of the complicating factors in oil production is the deposition paraffin, as a result of which the production well rate is decreasing and the Electric submersible pump failure occurs. The main factors influencing the intensity of paraffin formation are: downhole temperature, gas evolution, hydrocarbon composition in each phase of the mixture, high viscosity of oil, change in the velocity of the gas-liquid mixture. To solve problems, the thermal method is used, which consists in artificial increase of the well ...
