	Peculiarities of producing oil wells drowning in fractured reservoirs are considered. New effective gel-forming composition on sodium silicate base intended for water-shutoff and injectivity profile leveling in fractured reservoir conditions of Yaregskoe and Usinskoe oil fields is proposed. The results of the composition’s filtration experiments are presented. It is shown that the offered gel-forming composition could be successfully used for water shutoff in fractured complex structure reservoir conditions and also in cases of light oil reservoirs of complex structure and of different lithologic composition. Key words: extra heavy oil, complex structure reservoirs, fracturing of rocks, gel-forming compositions, flow resistance factor, selectivity.
