According to method, injected into annular space is oil and it is force-displaced through pump-compressor tube string. Selected for treatment is well located in zone where bed pressure is by 30-40% lower, or bed pressure in well zone is reduced by 30-40%. Used for injection is dewatered degassed oil heated to temperature of 100-150 C. Heated oil is pumped-through at volume of not less than 2 volumes of well.
