FIELD: oil extractive industry.
SUBSTANCE: method includes consecutive feeding into influx area of polymer compound and cement suspension, polymer compound has hardening time 90-120 minutes, feeding of cement suspension is performed after pumping of separator liquid having concurrently properties of hardening agent for polymer compound and accelerating agent for hardening of cement suspension, and before and after separating liquid additionally pumped are intermediate bodies of fresh water.
EFFECT: higher effectiveness of isolation of water influx areas by means of increasing stability of isolating border.
