FIELD: gas producing industry; applicable in repair operations for construction of gravel filters in well. SUBSTANCE: method includes injection into annular filtering space of gravel mixture containing particles of different fractional composition. Gravel mixture is prepared by mixing of three fractions of particles with the following amounts, vol.%: 0.4-0.8 mm fraction 10; 0.6-1.2 mm fraction 30-40; 1.2-1.8 mm 50-60.
