Summary:FIELD: oil and gas production industry. SUBSTANCE: this is intended for isolation or limiting of water inflow into wells and zones of absorption both in terrigenous and carbonate reservoirs, and for levelling of 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 resilient-flexible material and magnesium shavings in mass ratio of 3:1-15: 1. EFFECT: high efficiency. 1 tbla
