The paper presents a mathematical model for calculation of dynamic loads, which force a rod column and plunger of sucker rod pump in inclined well during pumping the multiphase fluid consisting of water, oil and gas. The mathematical model accounts for forces of boundary friction of rods and tube surface and viscous friction of rods and moving gas-liquid flow in the tubes, parameters of multiphase flow inside the tubes and annulus and also a variable type of pressure under the plunger space, phase transition and hydraulic losses. Results of simulation are compared with field measurements.
