FIELD: oil-and-gas producing industry; may be used in blocking or limiting water inflow to wells and lost circulation zones interrigenous and carbonate reservoirs, and equalization of injectivity profile in injection wells. SUBSTANCE: composition contains water-soluble polymer of acrylic series, sodium silicate, gel-formation regulator, filler and water. Filler is used in the form of sawdust modified with suspension of water-soluble viscous fluid and magnesium powder particles sizing 0.016-0.4 mm and contained in the amount of 10-50 wt.%. EFFECT: higher efficiency of shutoff of water inflow in wells. 4 cl
