FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil industry and can be used for treatment of bottomhole zone of production well. Proposed method comprises rupture of pump from support with application of autocrane on vehicle chassis to ensure fluid flow into tubing cavity, pumping of design volume of hydrocarbon solvent along tubing string into bottomhole zone of reservoir. Then, using the autocrane, the pump is put into the support, after which the hydrocarbon solvent is drained in the bottomhole formation zone by means of the DPE, after that, in the same sequence, acid solutions are pumped and drained, then the well is left to react to acid composition. After holding the well for reaction, the well is put into operation by the existing DPE with extraction of liquid to the flute tank with subsequent neutralization of the acid reaction products to the Ph of the formation.
EFFECT: technical result is higher efficiency of intensifying oil and gas production.
