FIELD: oil and gas production industry. SUBSTANCE: this is intended for isolation or limiting of water inflow to wells and zones of absorption both in terrigenous and carbonate reservoirs, and also for levelling injectivity profile in injection wells. According to method, injected compound has following components: water-soluble polymer of acrylic line, sodium silicate, gel-formation regulator, filler, and water. Used as filler are crumbles of porous resilient-flexible material and fine-dispersed aerogel at volume ratio of 1:5-1:50. EFFECT: high efficiency. 1 tbl
