The invention discloses an oil-electricity hybrid power system of a continuous oil pipe operation vehicle. The system is characterized by comprising an engine, a torsional vibration damper, a power takeoff, a transfer case, a hydraulic pump set, a planet row mechanism, a clutch mechanism, a motor device, a four-gear speed changer, a battery and a rear axle; the hydraulic pump set comprises a pump1, a pump 2, a pump 3, a pump 4 and a pump 5; the clutch mechanism comprises a first clutch, a second clutch and a third clutch; and the motor device comprises a first motor and a second motor. According to the oil-electricity hybrid power system, the double decoupling of the rotating speed and the torque of the engine is realized through the planet row mechanism, the problem of low working efficiency of the engine when the continuous oil pipe operation vehicle runs is solved, the economy of the whole vehicle is improved, meanwhile, the corresponding working mode of the system is switched according to the actual working condition, the reasonable utilization of energy is realized, and the reliability and the safety of the continuous oil pipe operation vehicle are enhanced on the premise ofensuring the power performance and the economy of the whole vehicle.
