The article described the developed technology for the phased removal of asphalt, resin and paraffin deposits in tubing using physical and chemical effects on the gas-liquid flow by pumping a mixture of organic acid, organic amine and organic solvents and a mixture of polyvinyl acetate, organic solvents and an activator into the bottomhole formation zone. The use of these mixtures can increase the technological and economic efficiency of gas-lift wells. As a result of industrial testing of the technology for the phased removal of asphalt, resin and paraffin deposits in tubing by the thermochemical method and inhibition of the formation of paraffin deposits by pumping reagents into the bottomhole formation zone with their subsequent gradual removal, a 100% effect was achieved in two wells of the White Tiger field.
