The paper presents the results of an experimental study of the temperature dependences of the viscosity of synthetic oil and the influence of ultrasonic effects on it. The effect of the oil component composition on the efficiency of ultrasonic treatment was investigated. Synthetic oil was a mixture of mineral oil with bitumen, the concentration of which ranged from 2% to 70%. The experimental data were obtained using a SV-10 vibrating viscometer; ultrasonic processing was carried out at a frequency of 22 kHz with an intensity of 10 W/cm2. It was established that the ultrasonic effect on the created oil samples as a whole leads to a decrease in viscosity. The maximum effect of viscosity reduction is observed at high temperatures and is more than 30%. With a low content of bitumen in oil, the effect of ultrasound is negative - the viscosity of the oil increases. The largest decrease in viscosity over the entire temperature range is observed in oil with a mass content of bitumen equal to 25% and averages 18.6%. The results can be used to improve the method of ultrasonic treatment of oil during its production and transportation.
