FIELD: oil extracting industry.
SUBSTANCE: reagent contains powder-like technical washing substance which includes no less than 4.5 percents of mass of surfactants, no less than 11 percents of mass of phosphorous-acidic salts in P2O3 equivalent and no less than 1.7 percents of mass of sodium silicate in SiO2 equivalent, sulphanol and polyacrylamide with following ratio of ingredients in percents of mass: technical washing substance 60-75; sulphanol 15-30, polyacrylamide - the rest. For removal of asphalt-resin-paraffin deposits it is used in form of 2-3% water solution, and for preventing asphalt-resin-paraffin deposits, it is used by means of placing in a perforated tank surrounded by oil.
EFFECT: asphalt-resin-paraffin deposits may be removed by means of reagent from surfaces of pipes footed by polyethylene, with concurrent increase of effectiveness of prevention of forming of asphalt-resin-paraffin deposits under such conditions, and higher ecological effectiveness.
