FIELD: oil and gas industry.
SUBSTANCE: perforator includes a perforator carrier passing in longitudinal direction, a charging pipe placed inside the perforator carrier and passing in longitudinal direction, a cumulative charge supported with the charging pipe, containing a bowl-shaped cover having a rim that forms a hole into the cover inner volume, lining inside the cover, and an explosive between the cover and the lining; besides, cumulative charge is directed in the first direction and has an axial line passing along the first direction being basically perpendicular to longitudinal direction, and liquid back fill located on outer side of the inner volume of bowl-shaped cover and near the cumulative charge in the first direction and crossing the axial line.
EFFECT: improvement of liquid communication with a reservoir in formations around the well.
