Summary: | oil production; applicable in shutoff of water inflow to bottom of producing wells. SUBSTANCE: method includes installation of hydraulic vibrator in tubing string in interval of injection of isolating jelling composition into formation. Before injection of isolating compound, injection interval is exposed to vibration treatment by hydraulic vibrator, in treatment of well for circulation. Isolating composition is injected into formation with flow rate ensuring operation of vibrator within frequency range of 50-100 Hz. EFFECT: provided needed intake rate in injection of gelling composition to producing well bottom-hole zone. |
