METHOD OF TRANSPORTING VISCOUS OIL AND OIL PRODUCTS VIA PIPELINE (VERSIONS) Russian patent published in 2009 - IPC F17D1/16 F15D1/02

Abstract RU 2350830 C1

FIELD: oil and gas industry.

SUBSTANCE: method consists in effecting oil in process of transporting with multi-frequency acoustic signal containing at least two monochromatic constituents, amplitudes and frequencies of which will satisfy condition of resonance overlapping, or, according to the second version of effect, to multi-frequency acoustic wide band signal with continuous spectrum of frequencies.

EFFECT: there is facilitated decreasing hydraulic resistance to flow of liquid in pipe, which accelerates rate of flow of liquid in pipeline.
