FIELD: oil industry.SUBSTANCE: group of inventions relates to oil and gas wells equipment. Method comprises heating a surrounding wall of an interior flow passage through which the well fluid flows, monitoring thickness variation of surrounding wall of an interior flow passage, caused by the accumulation of the substance in the flow passage. Monitoring is performed by a sensor from the group of sensors, containing a resistivity sensor, capacitance and inductance sensor. Heating is performed in response to the thickness variation of the wall which is greater than a predetermined level.EFFECT: higher efficiency of preventing hydrates, paraffins and waxes deposits formation.37 cl, 9 dwg |
