FIELD: oil and gas.
SUBSTANCE: invention may be used for the recovery of oil from wells with deep-well pumps. The method involves feeding oil treated with anti-seize agent to the pump suction. According to the invention, a loading dose of anti-seize agent is applied to the oil column in the annulus. Gradual influx of treated oil from the annulus to the pump suction is provided by natural pressure fluctuations in the well production gathering system. Based on the results of periodic deep-well pump dynamography, if required for one-time influx of treated oil, the casing valve on the wellhead is closed for a period of time sufficient for annulus pressure increase by 0.1-0.2 kgf/cm2.
EFFECT: protection of pump plunger pair against seizing.
