FIELD: oil and gas production.
SUBSTANCE: hydrophobic polymer backfilling composition for oil and gas wells containing pre-polymer, solvent and hardening accelerator, as hardening accelerator contains organic-bentonite clay powder at following ratio of components, wt shares: pre-polymer 100, solvent 50-100, organic-bentonite clay powder 1-1.5.
EFFECT: improved mechanic properties of hydrophobic polymer backfilling composition, reduced time for structure formation required for transition of backfilling composition from liquid state into gel at insulation operations in oil and gas wells.
