Detonating method capable of lowering interference among perforating charges

The invention discloses a detonating method capable of lowering interference among perforating charges. The method is characterized in that during perforating charge explosion, three independent perforating charge strings are set, and each perforating charge string comprises an external-winding high-detonation-velocity detonating cord, and the perforating charge interval of each perforating charge string is 77.9mm; after the first perforating charge string is detonated, the second perforating charge string is detonated 20 microseconds later, and the third perforating charge string is detonated 40 microseconds later; after a first perforating charge is detonated, impact waves generated by the explosion of the first perforating charge are loaded to a second perforating charge, a third perforating charge and a fourth perforating charge which are adjacent to the first perforating charge, the distance between the first perforating charge and the fourth perforating charge is 77.9mm, and the second perforating charg
