FIELD: oil and gas industry.
SUBSTANCE: invention is related to compounds intended for removing asphalt-resin-paraffin deposits (ARPD), and may be used for ARPD dissolution and removal from oil-field equipment, bottomhole formation zone, tubing strings, flow lines, pipelines, tanks and equipment of oil refineries. Composite for removing ARPD contains hydrocarbon solvents and includes dimethyl formamide and gas condensate additionally, toluene and nefras C2 80-120 are used as a hydrocarbon solvents with the following ratio of components, vol %: nefras C2 80-120 - 5-15; toluene - 25-35; dimethyl formamide - 3-7; gas condensate - remaining volume.
EFFECT: ratio of components ensures high dissolving efficiency for ARPD components.
