FIELD: chemistry.
SUBSTANCE: invention relates to the oil industry and can be used to clean pumping and compression pipes, pipelines, containers, reservoirs, pumps and well equipment from asphaltene-resin-paraffin deposits and mineral salts. The composition for cleaning oil equipment from asphaltene-resin-paraffin deposits and mineral salts contains the following, wt %: sodium alkylsulphonate 0.005-0.05, sodium alkylbenzene sulphonate 0.005-0.05, monoalkyl ester of polyethylene glycol 0.005-0.05, monoalkylphenyl ester of polyethylene glycol 0.005-0.05, alkali 0.05-2.00, water - the balance.
EFFECT: high efficiency of cleaning metal surfaces from asphaltene-resin-paraffin deposits and mineral salts, low corrosive activity of formation fluids on metals and alloys, longer time between repairs of wells and pipelines.
