SHAPED CHARGE FOR WELL PERFORATION

FIELD: oil production, particularly shaped-charge perforators. ^ SUBSTANCE: shaped charge includes three cumulative parts, namely central and two side ones tightly joined to central part so that all parts form a single piece. Central part is elongated and has constant symmetric cross-section. Side p...

Beschreibung
Zusammenfassung:	FIELD: oil production, particularly shaped-charge perforators. ^ SUBSTANCE: shaped charge includes three cumulative parts, namely central and two side ones tightly joined to central part so that all parts form a single piece. Central part is elongated and has constant symmetric cross-section. Side parts are defined by rotation of cross-section half through 180 angle about axis of symmetry. The shaped charge is placed in common body and has common facing formed of powder material. ^ EFFECT: increased perforation efficiency. ^ 3 dwg, 1 ex
