FIELD: oil and gas industry.
SUBSTANCE: method of supporting production reservoir of the gas well into the well implies pumping a binding composition, which is a mixture of reagents, containing 60-80 wt % of modified tetraethoxysilane and 20-40 wt % of aqueous acid catalyst solution. It is forced into the reservoir by a gaseous agent selected from group of gases: nitrogen, exhaust gases of internal combustion engine, carbon dioxide. At that, gaseous agent is fed to the well at a pressure exceeding reservoir pressure at least by 1.0 MPa. After that well is kept for process settling for at least two days.
EFFECT: reduced water saturation of reservoir bottom-hole zone, enhanced gas well deliverability with single treatment of reservoir.
