FIELD: oil production industry. SUBSTANCE: invention refers to utilization of polymer grouting mortars for isolation of productive pool inhomogeneous by penetrability and absorption zones. Method of isolation of productive pool includes pumping of mixture of polymerizing fluid and polymerization initiator into well and its curing during time necessary to form polymer. 6.5-10.0% solution of raw rubber in styrene or 10.0-20.0% solution of foam polystyrene with proportion 100:(0.5-3.0) of polymerizing fluid and polymerization initiator is used in the capacity of polymerizing fluid. Azoisobutyronitrile-porofor or dicetylperoxidicarbonate-lilodux or lauroile peroxide or tretbutylperbenzoate is utilized as polymerization initiator. Polymerizing fluid and polymerization initiator are mixed in the course of not more than 30 min in process of preparation of mixture. EFFECT: preparation of polymer product formed in total volume of reagents. 2 cl, 2 tbl
