Abstract: The article discusses the mathematical modeling of pressure on the plunger during the operation of oil wells with sucker rod pumps. The problem of determining the total pressure on the plunger during its upward movement in the riser during the operation of oil wells with a plunger lift is considered. For mathematical modeling of the process, generally accepted assumptions are made regarding the movement of liquid (oil) in the annular space between two cylindrical pipes, one of which moves relative to the other. A theoretical method is proposed for determining the total pressure on the plunger, taking into account the viscoelastic properties of the produced oil. Numerical experiments have studied the effect of the viscoelastic properties of oil on the change in the total pressure on the plunger.
