FIELD: pipeline engineering.
SUBSTANCE: method comprises making purifying gel-like piston by adding an inorganic acid to fresh water to provide solution of pH from 1.0 to 2.5. The water solution of formaldehyde is added to the mixture obtained in amount of 5-15% of the final composition and is mixed. Polyacrylamide is added at permanent mixing.
EFFECT: improved quality.
