FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to petroleum industry, particularly to preparation methods of gelling compounds for restriction of water production and adjustment of in-place permeability. In preparation method of gelling compound for limitation of water production and adjustment of in-place permeability, including blending while heating of silicate-bearing material, alkali and water, silicate-bearing material is previously subject to mechanical activation and while specified blending it is prepared suspension at following correlation of components, wt % : mechanically activated silicate-bearing material 30-60, alkali 1-15, water-the rest. In the capacity of silicate-bearing material there can be used sand or glass breakage. Received compound additionally can be filtered.
EFFECT: increasing of mechanical stability of received gel.
