Zusammenfassung:	FIELD: blasting operations. SUBSTANCE: invention is intended for use in oil and gas production industry when performing perforating operations in boreholes. Explosive core of detonating cord is made in the form of corrosion-resistant continuous flexible fiber containing explosive particles uniformly distributed in mass consisting of polymer mixture of rubbers reinforced by fluoroplastic particles, whereas shell is made from threads and is imbedded into side surface of fiber of explosive core of cord. Cord can be used both in casing-type and in casingless cumulative perforators. EFFECT: minimized shell of cord possessing high reliability of initiation of perforator charges. 6 cl, 1 dwg, 1 tbl
