FIELD: oil and gas production.
SUBSTANCE: invention refers to sealing compositions for remedial cementing which can be used for insulation of drill string-casing and casing string-borehole annuluses, multiple sealing of threaded casing pipe joint while high hydrogen sulphide oil and gas well operation. The sealing composition for remedial cementing contains, wt %: pine rosin 20-40, castor oil 0.5-1.0, and acetone - the rest.
EFFECT: higher efficiency of remedial cementing ensured by using the sealing compositions with improved processing characteristics, higher hydrogen sulphide aggression resistance.
