FIELD: chemical well treatment to decrease hydrogen sulfide content in gas space of well during well repair or survey including the cases of normal and low reservoir pressure.
SUBSTANCE: neutralization method for hydrogen sulfide present in well in gaseous and dissolved state involves injecting hydrogen sulfide neutralizing agent included in foam system in well. Gas-liquid foam system is obtained directly during injection operation by water contact with solid-phase foam generation composition including the hydrogen sulfide neutralizing agent.
EFFECT: increased technological efficiency.
