FIELD: oil pipeline maintenance. SUBSTANCE: to obtain gel-like composition with minimum time and manual labor expenditures and providing possibility of its self-utilization, as water-soluble polymer, bulk copolymer of alkylene oxides and ethylenediamine, and, as cross-linked agent, dimethyldiallylammonium chloride polymerization product in proportion 1:1 are used. Composition may find use for cleaning both main and field oil pipelines from moisture accumulations, solid particles and gases. EFFECT: facilitated cleaning process. |
