FIELD: oil production. SUBSTANCE: invention deals with ways insulating water in creviced formations and of lost circulation zones both in terrigenous and carbonate collectors. Way to insulate water in creviced formations includes injection of suspension of rubber crumbs in oil. Suspension is supplemented with organic flour and polymer with following proportion of components, per cent by weight: rubber crumbs 2.0-15.0; organic flour 1.0-20.0, polymer 0.1-0.5; oil being the balance. EFFECT: enhanced efficiency of water insulation in creviced formations and in lost circulation zones both in terrigenous and carbonate collectors. 1 dwg, 1 tbl
