FIELD: oil and gas industry.
SUBSTANCE: invention relates to the oil and other viscous products pumping, extraction and transportation technological processes. Oil viscosity reduction method, according to which the oil structure is subjected to the ultrasonic effect on the longitudinal wave frequency harmonic first carrier, emitted by the lithium niobate excited monocrystal, immersed in the oil environment, equal to 450.0 kHz, and with for 100 % amplitude modulated sinusoidal wave in the modulation frequency range from 0 to 100 kHz, which provide optimal energy conditions for viscosity reduction in various types of oil, starting from the temperature of 16 °C, at which oil flows laminarly, that is, without the flowing jet breaking.
EFFECT: technical result is increase in the ultrasound effectiveness for the viscosity reduction and, as a consequence, energy costs reduction.
