PROCEDURE FOR RECOVERY OF TIGHTNESS IN FLOW STRINGS Russian patent published in 2011 - IPC E21B29/10 E21B33/13

Abstract RU 2416020 C1

FIELD: oil and gas production.

SUBSTANCE: mineral binding - liquid glass and curing liquid are pumped into leakage zone of flow string. Further, binding is after-cured with cement grout. Also, oil for replacement of water is pumped into the well first. Further, there is pumped solution of liquid glass with curing liquid - fluor-silicate sodium at the following ratio of components %: liquid glass (Na₂SiO₃) 88-86 %, fluor-silicate sodium (Na₂SiF₆)12-14 %.

EFFECT: raised reliability of isolation in stopping leakage of casing in interval of well above pay zone.
