FIELD: oil and gas industry.
SUBSTANCE: along length of the pipeline at even intervals oil products are impacted by acoustic oscillations thus forming liquid layer of oil products near walls. Acoustic oscillations are excited as pulses with carrier frequency corresponding to resonant frequency of the pipeline by means of acoustic radiators fixed rigidly at outer wall of the pipeline with radiation intensity of 10-20 W/cm2 and duration of the impact of 10-60 minutes.
EFFECT: improved efficiency of high-viscous oil products transportation through pipeline.
