FIELD: oil and gas industry.
SUBSTANCE: well compression impulse generator includes housing with ignition initiation system, in which charge system is located. Housing of charge system represents thin-wall strip cover divided into sections with plastic bushes with central holes filled with material-retarder. At that, material-retarder includes mixture of black powder with particle size of 100 mcm with addition of 6% of nitromethane and 3% of aluminium powder.
EFFECT: providing action on well without damage to its integrity and seals of formation rock.
