FIELD: mining.
SUBSTANCE: control method of solid particles migration in underground formation section and method of creation of stabilised area around underground formation section around well bore, which has mesh filter or shank installed in the above section includes the following: putting of fluid medium for pre-washing in underground formation section; further putting of low-viscous adhesive diluted with water-soluble solvent and having viscosity of less than 100 centipoises to underground formation section; contact of low-viscous adhesive with small particles or formation sands located in underground formation section; at that, the treated section of underground formation has reduced permeability equal at least approximately to 70%; at that, low-viscous adhesive includes non-aqueous agent to increase adhesiveness, which also includes multifunctional material having the quantity of about 0.01% to about 50% as to weight of non-aqueous agent in order to increase adhesiveness. At that, multifunctional material includes at least one multifunctional material chosen from the group consisting of the following: aldehyde, dialdehyde, aldehyde releasing compound, dihalide, anhydride of polyacid, epoxide, furfuraldehyde, condensation product of glutaric dialdehyde, condensation product of aldehyde and any their combination.
EFFECT: decreasing the probability of damage to underground formation and well bore with simultaneous economic effect.
