FIELD: oil and gas industry.
SUBSTANCE: treatment method of some portion of underground formation during preparation for operation of hydraulic formation fracturing involves: liquid supply for preliminary packing to some portion of underground formation including non-tight materials in the form of particles. At that, liquid for preliminary packing includes low-viscous water composition for increasing adhesive ability, which itself contains water compound to increase adhesive ability, and water fluid. At that, low-viscous water composition intended to increase adhesive ability has viscosity which is approximately less than 100 cP; liquid supply for hydraulic formation fracturing to some portion of underground formation at the pressure which is enough to create or enlarge at least one fracturing in it; activation of water compound to increase adhesive ability with activator in order to bind non-tight materials in the form of particles within the portion of underground formation.
EFFECT: combination of materials in the form of particles to bound elastic mass.
