FIELD: oil and gas industry.
SUBSTANCE: method of bottomhole support in the formation with unstable rocks includes generation of a filter by preparation and injection of the polymer composition to the bottomhole zone. Before and after these operations a solution is injected which makes 10-30% by volume of the polymer composition. Thereafter the well is blown by a flow of gas and withhold for the composition reacting and curing. At that a mixture of silicone resin and solution Chimeco-P is used as the polymer composition in quantity of 95.0-98 wt %: hardener AGM-9 - 5-.0-2.0 wt % representing aminopropyltriethoxysilane. A mixture of xylol or a mixture of rectification residues KORE in quantity of 0.0-100 wt % and aromatic solvent Nefras A in quantity of 100.0-0.0 wt % is used as the solvent.
EFFECT: increased efficiency of the method.
