FIELD: oil industry.
SUBSTANCE: invention relates to pipeline transportation of oil, oil products and gas condensate and is intended for cleaning pipelines from asphalt-resin-paraffin deposits, oil-water emulsions and formation water. The composition of a multifunctional gel piston for cleaning main pipelines from deposits includes a water-soluble or partially cross-linked polyacrylamide, a hydrocarbon liquid, an inorganic cross-linking agent, an oligomer and water, and a urea-formaldehyde or urea-melamine-formaldehyde resin is used as an oligomer.
EFFECT: obtaining material with improved environmental and elastic performance characteristics.
