An oil-electric hybrid power system for a coiled tubing operation vehicle

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of special petroleum vehicles, and more precisely, the invention relates to a hybrid power system of a coiled tubing operation vehicle. Background technique [0002] At present, special petroleum vehicles include fracturing vehicles, tank trucks, drilling vehicles, coiled tubing operation vehicles, etc. Special petroleum vehicles such as fracturing vehicles and drilling vehicles are used less frequently, so the number of attendance is relatively low. As an important vehicle for arranging sucker rods, the coiled tubing vehicle also has functions such as workover, drilling, completion, logging, and production stimulation. Every well needs to undergo fixed maintenance every year. Therefore, the coiled tubing vehicle has become a special petroleum vehicle. It is the most frequently used vehicle in the vehicle, and improving the economy of the coiled tubing operation vehicle can save a lot of money. However, bec...
