Abstract: FIELD: petroleum industry. 
     SUBSTANCE: invention relates to the technique of production of commercial oil and can be used at production enterprises of the oil processing and oil production industry for development of apparatus for super high-frequency (SHF) treatment of water-oil emulsions. The invention provides higher quality of separation of water-oil emulsion by increasing the number and intensity of contacts of water drops in the flow of water-oil emulsion under the influence of SHF energy in the intertubular zone formed in the segment of the pipeline by the surface of the guiding structure and the pipeline walls and reduction of consumption of electromagnetic SHF supplied to the inlet of the SHF energy input assembly of the open guiding structure. The method envisages formation of distribution of SHF energy losses from the source of SHF energy in the flow of water-oil emulsion, using the process of attenuation of external filed of the electromagnetic wave of the open guiding structure characterised in water-oil emulsion transported through the pipeline by selected specified distribution of the of external electromagnetic filed parallel to the guiding structure by passing the flow of water-oil emulsion in the intertubular zone through a structure of elements of the type assigned fabricated from dielectric materials and installed in the intertubular zone parallel to the open guiding structure in the direction of the flow of water-oil emulsion, and the minimal permissible duration of influence of electromagnetic energy on water-oil emulsion required is set by varying flow rate Q of water-oil emulsion in the flow through the pipeline within the range 0<Q≤Q max =(S p -S l )L/t min , where Q - flow rate of water-oil emulsion in the pipeline, Q max  - maximal flow rate of water-oil emulsion, L - length of the open distributed guiding structure in the pipeline, t min  - minimal permissible duration of influence of electromagnetic energy on water-oil emulsion, S l  - cross-section area of the open distributed guiding structure, S p  - cross-section area of the pipeline. The apparatus for micro-wave treatment of the flow of water-oil emulsion, transported through the pipeline, containing the source of SHF energy with the assembly for input of SHF energy into the pipeline made in the shape of an open guiding structure with length L in the intertubular zone parallel to the open guiding structure of length L, determined by the formula L=(t min Q max )/(S p -S l ) )  is provided with a structure of elements of the type assigned, fabricated from dielectric materials and orientated parallel to the axis of the open guiding structure, and the pipeline is fitted with a gate mounted from the side of input into the intertubular zone with cross-sectional area of the through bore S g , varying within the limits 0<S g <S p . 
     EFFECT: higher quality of separation of water-oil emulsion, and reduction of consumption of electromagnetic SHF energy supplied to the inlet of the SHF energy input assembly of the open guiding structure.
